ds_q48s q 120 33 _ 0927 2013 7 design consideration s input source impedance the impedance of the input source connecting to the dc/dc p ower modules will interact with the modules and affect the stability. a low ac - impedance input source is recommended. if the source inductance is more than a few h, we advise adding a 10f to 100f electrolytic capacitor (esr < 0.7 at 100 khz) mounted close to the input of the module to improve the stability. layout and emc considerations deltas dc/dc power modules are designed t o operate in a wide variety of systems and applications. for design assistance with emc compliance and related p w b layout issues, please contact deltas technical support team. an external input filter module is available for easier emc compliance design. below is the reference design for an input filter tested with q48sq12033 series to meet class b in cisspr 22. schematic and components list: c in is 100uf low esr aluminum cap: cy is 1nf ceramic cap ; cx1 is 1uf*3 ceramic cap; cx2 is 1uf*2 ceramic cap; cy 1,cy2 are 100 nf *2 ceramic cap : l1,l2 are common - mode inductor,l1=l2=0.47mh. test result: vin=48v,io=33a, b lue l ine is quasi peak mode; green line is average mode. safety considerations the power module must be installed in compliance with the spacing an d separation requirements of the end - users safety agency standard, i.e., ul60950 - 1, can/csa - c22.2 , no. 60950 - 1 and en60950 - 1+a11 and iec60950 - 1 , if the system in which the power module is to be used must meet safety agency requirements. basic insulatio n based on 75 vdc input is provided between the input and output of the module for the purpose of applying insulation requirements when the input to this dc - to - dc converter is identified as tnv - 2 or selv. an additional evaluation is needed if the source i s other than tnv - 2 or selv. when the input source is selv circuit , the power module meets selv (safety extra - low voltage) requirements. if the input source is a hazardous voltage which is greater than 60 vdc and less than or equal to 75 vdc, for the modul es output to meet selv requirements, all of the following must be met: ? the input source must be insulated from the ac mains by reinforced or double insulation. ? the input terminals of the module are not operator accessible. ? if the metal baseplate is gro unded , the output must be also grounded. ? a selv reliability test is conducted on the system where the module is used , in combination with the module, to ensure that under a single fault, hazardous voltage does not appear at the modules output. when inst alled into a class ii equipment (without grounding), spacing consideration should be given to the end - use installation, as the spacing between the module and mounting surface have not been evaluated. the power module has extra - low voltage (elv) outputs wh en all inputs are elv. this power module is not internally fused. to achieve optimum safety and system protection, an input line fuse is highly recommended. the safety agencies require a normal - blow fuse with 2 0a maxim um rating to be installed in the ungr ounded lead. a lower rated fuse can be used based on the maximum inrush transient energy and maximum input current. soldering and cleaning considerations post solder cleaning is usually the final board assembly process before the board or system undergoe s electrical testing. inadequate cleaning and drying may lower the reliability of a power module and severely affect the finished circuit board assembly test. adequate cleaning and drying is especially important for un - encapsulated and/or open frame type p ower modules. for assistance on appropriate soldering and cleaning procedures, please contact deltas technical support team. 1 mhz 10 mhz 150 khz 30 mhz 10.0 20.0 30.0 40.0 50.0 60.0 70.0 0.0 80.0 dbv limits 55022mqp 55022mav transducer lisnpul traces pk+ av
ds_q48s q 120 33 _ 0927 2013 8 features description s over - current protection the modules include an internal output over - current protection circuit, which wil l endure current limiting for an unlimited duration during output overload. if the output current exceeds the ocp set point, the modules will shut down (hiccup mode) . the hiccup time will last 500ms. the modules will try to restart after shutdown. if the o verload condition still exists, the module will shut down again. this restart trial will continue until the overload condition is corrected. over - voltage protection the modules include an internal output over - voltage protection circuit, which monitors t he voltage on the output terminals. if this voltage exceeds the over - voltage threshold , the modules will shut down, ( latch mode) . the module will not restart unless the on/off input is toggled or the input power is cycled. over - temperature protection th e over - temperature protection consists of circuitry that provides protection from thermal damage. if the temperature exceeds the over - temperature threshold the module will shut down. the module will restart after the temperature is within specification. r emote on/off the remote on/off feature on the module can be either negative or positive logic. negative logic turns the module on during a logic low and off during a logic high. positive logic turns the modules on during a logic high and off during a logi c low. remote on/off can be controlled by an external switch between the on/off terminal and the v i ( - ) terminal. the switch can be an open collector or open drain. for negative logic i f the remote on/off feature is not used, please short the on/off pin to vi ( - ). for pos i tive logic i f the remote on/off feature is not used, please leave the on/off pin to floating . figure 16 : remote on/off implementation remote sense remote sense compensates for voltage drops on the output by sensing the actual outp ut voltage at the point of load. the voltage between the remote sense pins and the output terminals must not exceed the output voltage sense range given here: [vo(+) C vo( C )] C [sense(+) C sense( C )] 10% v out this limit includes any increase in voltag e due to remote sense compensation and output voltage set point adjustment (trim). figure 1 7 : effective circuit configuration for remote sense operation if the remote sense feature is not used to regulate the output at the point of load, please connec t sense(+) to vo(+) and sense( C ) to vo( C ) at the module . the output voltage can be increased by both the remote sense and the trim; however, the maximum increase is the larger of either the remote sense or the trim, not the sum of both. when using remote sense and trim, the output voltage of the module is usually increased . and it will increase the output power of the module with the same output current. care should be taken to ensure that the maximum output power does not exceed the maximum rated power . vo(+) vi(+) vo(-) sense(-) sense(+) vi(-) on/off vi(-) vi(+) vo(-) vo(+) sense(+) sense(-) resistance contact contact and distribution losses
ds_q48s q 120 33 _ 0927 2013 9 thermal consideratio ns thermal management is an important part of the system design. to ensure proper, reliable operation, sufficient coolin g of the power module is needed over the entire temperature range of the module. convection cooling is usually the dominant mode of heat transfer. hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. thermal testing setup deltas dc/dc power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. this type of equipment commonly uses vertically mounted circuit cards i n cabinet racks in which the power modules are mounted. the following figure shows the wind tunnel characterization setup. the power module is mounted on a test pwb and is vertically positioned within the wind tunnel. the space between the neighboring pwb and the top of the power module is constantly kept at 6.35mm (0.25). f igure 20: win d t unnel t est s etup thermal derating heat can be removed by increasing airflow over the module. to enhance system reliability, the power module should always be oper ated below the maximum operating temperature. if the temperature exceeds the maximum module temperature, reliability of the unit may be affected. output voltage adjustment (trim) to increase or decrease the output voltage set point, the modules may be connected with an external resistor between the trim pin and either the sense(+) or sense( - ). the trim pin should be left open if this feature is not used. trim down: figure 1 8 : circuit configuration for trim - down (decrease output voltage) if the external resistor is connected between the trim and sense ( - ) pins, the output voltage set point decreases (fig. 1 8 ). the external resistor value re quired to obtain a percentage of output voltage change % is defined as: trim up: figure 1 9 : circuit configuration for trim - up (increase output voltage) if the external resistor is connected between the trim and sense ( + ) the output voltage set point increases (fig. 1 9 ). the extern al resistor value require d to obtain a percentage output voltage change % is defined as: air flow module pwb 50.8(2.00") air velocity and ambient temperature sured below the module fancing pwb note: wind tunnel test setup figure dimensions are in millimeters and (inches) ? ? ? ? ? ? ? k down rtrim 2 . 10 511 ? ? ? ? ? ? ? ? ? ? ? k up rtrim 2 . 10 511 1.225 ) (100 vo 11 . 5
