This series of converters does not require any external components for proper operation. However, if the distribution of the input voltage to the converter contains significant inductance, a capacitor across the input terminals may be required to stabilize the input voltage. A minimum of 1F, quality electrolytic / ceramic capacitor is recommended for this purpose. For output decoupling it is recommended to connect, directly across the output pins, a 1F ceramic capacitor (for 3.3V and 5V outputs) or a 0.27F ceramic capacitor (for 7V and 12V outputs).
Turn-On Input Voltage
(Note:- this feature is not available on 4:1 input range devices, RNS01EE/RNS01EG/RNS0.9ET) An external resistor can program the input voltage at which the converter switches on. The voltage at which the unit switches off is typically 1V below the turn-on input voltage (Vion). The characteristic curves below shows the typical resistor values required to achieve adjustment of turn-on input voltage (Vion). To decrease Vion the resistor connected between pins 10 and 11.

Remote Control Feature
The remote control pin functions as a normal soft shutdown. It is referenced to the -Vin pin. With positive logic, when the remote control pin is pulled low, the output is turned off and the unit goes into a very low input power mode. An open collector switch is recommended to control the voltage between the remote control pin and the -Vin pin of the converter. The remote control pin is pulled up internally, so no external voltage source is required. The user should avoid connecting a resistor between the remote control pin and the +Vin pin. The user must take care to ensure that the pin reference for the control is connected close to the -Vin pin. The control signal must not be referenced ahead of EMI filtering, or remotely from the unit. If the remote control pin is not used, it can be left floating.

Voltage (Vion)
To increase Vion the resistor should be connected between pins 11 and 17.

Synchronization Feature
It is possible to synchronize the switching frequency of one or more converters to an external symmetrical clock signal. It is recommended that the signal be driven by a TTL compatible output. The rise time of the clock signal should be less than 10ns. If the synchronization feature is not used, it should be left open circuit.

Note: For setting nominal output voltage pin 8 must be connected to pin 9. The trim feature allows the user to adjust the output voltage from the nominal. This can be used to accommodate a different requirement or to do production margin testing. Output voltage can be adjusted by an external resistor. If pin 8 and pin 9 are not connected together the output will decrease to a low value. To increase Vo a resistor should be connected between pin 8 / 9 and pin 17 ( -Vin). To decrease Vo, a resistor should be connected between pin 8 and 9 (NOR). To increase Vo: Radj = A x (B - Vd) / (Vd - Vo) k Where: Vd = Desired output voltage Vo = Nominal output voltage. To reduce Vo: Radj = C x (Vo - Vd) / (Vd - D) k Where: Vd = Desired output voltage Vo = Nominal output voltage.

Output Current Limiting
When the output is overloaded above the maximum output current rating, the voltage will start to reduce to maintain the output power to a safe level. In a condition of high overload or short-circuit where the output voltage is pulled below approximately 30% of Vo.Nom, the unit will enter a `Hiccup' mode of operation. Under this condition the unit will attempt to restart, approximately every 100ms until the overload has cleared.
Parallel Operation
Paralleling of two converters is possible by direct connection of the output voltage terminal pins. The load regulation characteristic is designed to facilitate current sharing (typically 20%).
Thermal Considerations
The converter is designed for natural or forced convection cooling. The output power of the converter is limited by the maximum case temperature (Tc). To ensure reliable long term operation of the converters, and to comply with safety agency requirements, Power-One limits maximum allowable case temperature (Tc) to 110C (see Mechanical Drawings).
Notes: 1. When the output voltage is trimmed up, the output power from the converter must not exceed its maximum rating. This is determined by measuring the output voltage on the output pins, and multiplying it by the output current. 2. The trim feature allows the generation of additional standard voltages such as 2.5V from 3.3V model, 15V from 12V model and 6V or 8V from the 7V model. 2-Nov-01 Rev 1.1 www.power-one.com Page 11 of 16

These converters feature 1500 Volt DC isolation from input to output. The input to output resistance is greater than 10MOhm. These converters are provided with Operational Insulation between input and output circuits according to EN60950 / UL1950 / CSA60950-00. Nevertheless, if the system using the converter needs to receive safety agency approval, certain rules must be followed in the design of the system. In particular, all of the creepage and clearance requirements of the end-use safety requirements must be observed. These documents include UL60950, CSA60950-00 and EN60950, although specific applications may have additional requirements. In order for the output of the converter to be considered as SELV (Safety Extra Low Voltage) or TNV-1, according to EN60950 / UL1950 / CSA60950-00, one of the following requirements must be met in the system design: * The converter has no internal fuse. The external fuse must be provided to protect the system from catastrophic failure. The fuse with a rating not greater than 2.0A is recommended. The user can select a lower rating fuse based upon the inrush transient and the maximum input current of the converter, which occurs at the minimum input voltage. Both input traces and the chassis ground trace (if applicable) must be capable of conducting a current of 1.5 times the value of the fuse without opening. The fuse must not be placed in the grounded input line, if any. * If the voltage source feeding the module is SELV, the output of the converter is considered SELV and may be grounded or ungrounded. * The components on the converter carry transients, which exceed the input voltage. Even if the input voltage is SELV (<60V) the components on the primary side of the converter may have to be considered as hazardous. A safety interlock may be needed to prevent the user from accessing the converter while operational. 2-Nov-01

Soldering: The following instructions must be observed when soldering the unit. Failure to observe these instructions may result in failure or significant degradation of the module performance. PowerOne will not honor any warranty claims arising from failure to observe these instructions. This product is approved for forced convection reflow soldering only. The curves below define the maximum peak reflow temperature permissible measured on Pins 1 and 10 of the converter. The lead-frame is constructed from a high temperature glass filled, UL94V0 flame retardant, diallyl ortho-phthalate moulding compound commonly used for packaging of electronics components. It has passed NASA outgassing tests and is certified to MIL-M-14. The coefficient of thermal expansion is equivalent to FR4. The gull wing leads are formed to ensure optimal solder joint strength and structure. Furthermore they facilitate visual inspection (manual or automatic). The leads are formed from a 97% Cu alloy plated with Cu and Sn 90. This material is commonly used in the manufacture of integrated circuits. It has good corrosion resistance and exhibits the nobility inherent to all high copper alloys. Unlike brasses, this material is essentially immune to stress corrosion cracking. It also exhibits excellent solderability. It is readily wetted by solders and performs well in standard solderability tests. (Dip of Class II or better). The product is manufactured with a patented process, which is fully automated, and `in-line'. This ensures that there is no contamination or mechanical stress on the lead-frame so that the co planarity and solderability are maintained. The product is shipped in JEDEC trays to guarantee preservation of the co-planarity and enable fully automated assembly in the final application. .

Pick & Place Assembly: The product is designed with a large flat area in the center of the top surface to serve as a pick up point for automated vacuum pick and place equipment. The `open board' construction of the unit ensures that weight is kept to a minimum. However due to the relatively large size of the component, a large nozzle (> 4.0mm, depending on vacuum pressure) is recommended for picking and placing. The unit may also be automatically handled using `odd-form' placement equipment, with mechanical grippers. For this type of equipment the end edges of the device, which have no leads and also feature the greatest dimensional accuracy, should be used as pick-up points. Page 13 of 16
