| (R) (R) A SUBSIDIARY OF C&D TECHNOLOGIES Mixed Voltage, BCP Models Dual Output 5V and 3.3V, "Half-Brick" 75 Watt, DC/DC Converters Features Independent 5V and 3.3V outputs Each output fully regulated No minimum load requirements Up to 15 Amps per output 75 Watts total output power Standard "half-brick" package UL1950, EN60950 and VDE safety approvals (BASIC insulation) Fully isolated, 1500Vdc guaranteed 18-36V or 36-75V input ranges mark available (75V-input models) Input under and overvoltage shutdown Continuous short-circuit protection Thermal shutdown As your new, mixed-logic (5V and 3.3V) design evolves and your current requirements change, your new DC/DC converter will not. DATEL's BCP-5/15-3.3/15-D24 (18-36V input) and BCP-5/15-3.3/15-D48 (36-75V input) are fully isolated DC/DC converters providing both 5V and 3.3V outputs. Housed in standard "half-brick" packages (2.3" x 2.4" x 0.525"), the BCP's can support any combination of 5V and 3.3V loading up to a combined total of 15 Amps. Both outputs are fully isolated (1500Vdc) and independently line (0.2%) and load (0.5% and 0.6%) regulated. Both BCP models feature input pi filters, input undervoltage and overvoltage shutdown, input reverse-polarity protection, output overvoltage protection, current limiting, and thermal shutdown. Each has an on/off control function, and the two output voltages can be trimmed independently. BCP Model DC/DC's deliver low noise (50mVp-p), high efficiency (87%) and are fully specified for -40 to +100C operation. Utilization of metal baseplate technology with threaded inserts permits easy heat-sink attachment and/or pcb mounting. These devices meet IEC950, UL1950, EN60950 and VDE safety standards, including BASIC insulation requirements. CB reports are available on request.

The +5V Return (pin 6) and +3.3V Return (pin 9) are connected internal to the DC/DC converter. Though the returns are common within the DC/DC converter, the regulating control loop for each output is sensed directly at its respective output and return pins. In order to maintain optimum regulation if ground plane is not used, it is critical that PC board layouts also return each output to its corresponding return pin. Filtering and Noise Reduction All BCP DC/DC Converters achieve their rated ripple and noise specifications using the external input and output capacitors specified in the Performance/ Functional Specifications table. In critical applications, input/output noise may be further reduced by installing additional external I/O caps. Input capacitors should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors should be selected for low ESR and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted as close to the converters as possible. The most effective combination of external I/O capacitors will be a function of your particular load and layout conditions. Our Applications Engineers will be pleased to recommend potential solutions and can discuss the possibility of our modifying a device's internal filtering to meet your specific requirements. Contact our Applications Engineering Group for additional details. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For DATEL BCP DC/DC Converters, you should use slowblow type fuses with values no greater than the following. VIN Range "D24" Models "D48" Models Fuse Value 6 Amps 4 Amps Input voltages exceeding the input overvoltage shutdown specification listed in the Performance/Functional Specifications will cause the device to shutdown. A built-in hysteresis (2V typical for "D24" models, 4V typical for "D48" models) will not allow the converter to restart until the input voltage is sufficiently reduced. Start-Up Time The VIN to VOUT start-up time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fullyloaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input voltage as it appears to the converter. The On/Off to VOUT start-up time assumes the converter has its nominal input voltage applied but is turned off via the On/Off Control. The specification defines the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its specified accuracy band. On/Off Control (Standard feature) The On/Off Control (pin 3) may be used for remote on/off operation. As shown in Figure 1A, the control pin is referenced to the -Input (pin 1) and will be pulled to a high state internally. The standard BCP converter (no suffix) is designed so that it is enabled when the control pin is left open and disabled when the control pin is pulled low (to less than +0.6V relative to -Input). Dynamic control of the on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). The drive circuit should be able to sink approximately 1mA for logic low. The on/off control function is designed such that the converter can be disabled (pin 3 pulled low for no-suffix models) while input power is ramping up and then "released" once the input has stabilized. For BCP converters configured with the negative-polarity option on the On/Off Control pin ("N" suffix added to part number), operation is opposite to that described above. The converter is disabled when the On/Off Control pin is left open and enabled when pulled low. 3.3V Fuses should be installed in the +Input line. Input Overvoltage/Undervoltage Shutdown and Start-Up Threshold Under normal start-up conditions, devices will not begin to regulate until the ramping-up input voltage exceeds the Start-Up Threshold Voltage (35V for "D48" models). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown limit (32V for "D48" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built-in hysteresis prevents any unstable on/off situations from occurring at a single voltage. 4 +INPUT 21k 4 +INPUT 100k 3 ON/OFF CONTROL 3 ON/OFF CONTROL 1 1 -INPUT -INPUT Figure 1A.

"N" Suffix 4 7 5 W, D UA L O U T P U T, M I X E D - VO LTAG E D C / D C C O N V E R T E R S BCP Models Output Overvoltage Protection Each voltage output of the BCP Series converter is independently monitored via an auxiliary winding in the output inductor. If the output voltage should rise to a level which could be damaging to the load circuitry (see Performance/Functional Specifications for limits), the overvoltage circuitry will power down the PWM controller and latch off the DC/DC converter. The device must now be restarted by powering cycling VIN. Current Limiting When output current demands exceed the maximum output current rating by 107% to 133%, the DC/DC converter will go into a current limiting mode. In this condition the output voltage decreases proportionately as the output current increases, thereby maintaining a somewhat constant power dissipation--referred to as Power Limiting (see Figure 2). As the load approaches a short circuit, the output current will continue to increase until it reaches the rated Short Circuit Current limit. BCP-5/15-3.3/15-D24, D48 Current Limiting Characteristics (Nominal VIN) 6.00 Input Reverse-Polarity Protection Upon applying a reverse-polarity voltage to the DC/DC converter, an internal diode will be forward biased and draw excessive current from the power source. Therefore, it is required that the input current be limited be either an appropriately rated input fuse or a current limited power source. Heat Sinks for BCP Series DATEL offers two standard heat sinks that can be mounted to the half-brick package to extend the converter's operating temperature range. Along with the standard 2.3" x 2.4" x 0.5" (HS-CP) heat sink, DATEL has designed a low-profile heat sink for height-restricted applications. This new heat sink (HS-CPLP2) is designed with radiant fins that extend 0.51" beyond either side of the 2.4" dimension of the BCP package. The convenience of this design is that the finned extensions protrude only 0.31" below the top surface of the DC/DC converter, allowing components with a profile height less than 0.215" to be mounted on the pc board below the heat sink. Therefore, while the surface area of the low-profile heat sink measures 2.3" x 3.5", pcb real estate is unaffected. For optimum thermal performance in a natural convection application, the low-profile heat sink should be mounted with the fins vertically oriented. Both models are shipped with 0.009" sellf-adhesive thermal pad and mounting screws. 6 5.00 Output Voltage VOUT (Volts) 5V Output 4.00 3.00 2.00 C WATT THERMAL RESISTANCE 5 4 3.3V Output 1.00 HS-CPLP2 3 2 1 0 0 100 200 300 400 500 600 700 AIR VELOCITY (FT./MIN.) 0 24 25 15.2 15.7 16.2 16.7 17.2 17.8 18.3 18.8 19.3 19.8 20.3 20.9 21.9 22.4 Output Current, IOUT (Amps) Figure 2. Current Limiting Characteristics Short Circuit Condition As described under "Current Limiting," when the BCP Series DC/DC converter output is subjected to a short circuit condition, the output current will remain at the Short Circuit Current limit. In this state there is negligible power dissipated in the load. Therefore, most of the input power is dissipated within the converter, causing the internal temperature to increase. If this condition persists, Thermal Shutdown will activate and shutdown the DC/DC converter. When the internal temperature is sufficiently decreased, the converter will self-start. Thermal Shutdown The BCP Series is equipped with Thermal Shutdown circuitry. If the internal temperature of the DC/DC converter rises above the designed operating temperature, a precision temperature sensor will power down the unit. When the internal temperature decreases below the threshold of the temperature sensor the unit will self-start. 22.6 23.5 26 HS-CP HS-CP and HS-CPLP2 Heat Sink Performance Vs.

The trimpot can be used to determine the value of a single fixed resistor. A single fixed resistor can increase or decrease the output voltage depending on its connection.

Per the Ordering Guide on page 2, the trailing input voltage range (D24 or D48) in each part number pertains to the base part number. Part-number suffixes are added after the "input range," indicating the selection of standard options. The resulting part number is a "standard product" and is available to any customer desiring that particular combination of options, as described below. Suffix Blank Description On/Off Control function with positive polarity on pin 3 and independent trim function on either output (5V trim on pin 5 and 3.3V trim on pin 8). The pin length remains at 0.2 inches (5.08 mm). On/Off Control function with negative polarity on pin 3. Trim the pin length to 0.110 0.010 inches (2.79 0.25mm). This option requires a 100-piece minimum order quantity. Trim the pin length to 0.145 0.010 inches (3.68 0.25mm). This option requires a 100-piece minimum order quantity. Adaptations There are various additional configurations available on BCP 75W DC/DC Dual Half-Bricks. Because designating each of them with a standard part-number suffix is not always feasable, DATEL assigns a 5-digit "adaptation code" after the part-number suffixes. Once a configuration has been requested by a customer and created by DATEL, the resulting product is available to any customer as a "standard" off-the-shelf product. Contact DATEL directly if you are interested in your own set of options/adaptations. Our policy for minimum order quantities may apply. Consequently, the following product is offered for sale: BCP-5/15-3.3/15-D48-30752 Standard product, 48VIN, 5V/15A and 3.3V/15A Outputs with positive On/Off logic and modified VOUT Trim functions (pin 5 and 8 positions) to be compatible with Power-One's HBD-series. Adapted low profile packaging of 0.5 inches (12.7 mm) and with trimmed pin length to 0.15 inches (3.8 mm). N L1 L2 (R) (R) DATEL (UK) LTD.
