Capacitor mounted close to the input of the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0 at 100 KHz) capacitor of a 10F for the 5V input devices, a 4.7 F for the 12V and a 2.2F for the 24V and 48V devices. 4 Design & Feature Considerations Maximum Capacitive Load Soldering and Cleaning Considerations The DIHW1000 series has limitation of maximum connected capacitance at the output. The power module may be operated in current limiting mode during start-up, affecting the ramp-up and the startup time. The maximum capacitance can be found on page 2 of this datasheet. Post solder cleaning is usually the final board assembly process before the board or system undergoes electrical testing. Inadequate cleaning and/or drying may lower the reliability of a power module and severely affect the finished circuit board assembly test. Adequate cleaning and/or drying is especially important for un-encapsulated and/or open frame type power modules. For assistance on appropriate soldering and cleaning procedures, please contact Delta's technical support team. Output Ripple Reduction A good quality low ESR capacitor placed as close as practicable across the load will give the best ripple and noise performance. To reduce output ripple, it is recommended to use 3.3F capacitors at the output. + +Vin - -Vin + +Vin - Cout Load -Out +Out Dual Output DC / DC Com. Converter DC Power Source 1. These power converters require a minimum output load to maintain specified regulation (please see page 2 for the suggested minimum load). Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed above. 2. These DC/DC converters should be externally fused at the front end for protection. +Out Single Output DC / DC Converter DC Power Source Notes: -Vin -Out Cout Load Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from voltage control to current control. The unit operates normally once the output current is brought back into its specified range. 5 THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling 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 Delta's 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 in cabinet racks in which the power modules are mounted.

The power module is mounted on a test PWB and is vertically positioned within the wind tunnel. The space between the facing PWB and PWB is constantly kept at 25.4mm (1''). Figure 7: Wind tunnel test setup Thermal Derating Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected. 6 MODEL LIST INPUT MODEL NAME Vdc (V) OUTPUT Max (mA) Vdc (V) Max (mA) Full Load Efficiency Min (mA) % DIHW1002 857 5 600 90 70 DIHW1003 800 12 250 37.5 75 800 24 125 18.8 DIHW1006 800 12 125 18.8 76 75 DIHW1007 800 DIHW1012 338 15 5 100 600 15 90 DIHW1013 313 12 250 37.5 DIHW1008 5 (4.5 ~ 18) 75 74 313 24 125 18.8 80 81 313 12 125 18.8 80 DIHW1017 313 160 100 600 15 90 80 DIHW1022 15 5 DIHW1023 151 12 250 37.5 83 DIHW1028 151 24 125 18.8 84 151 12 125 18.8 83 DIHW1027 151 80 100 600 15 90 83 DIHW1032 15 5 DIHW1033 75 12 250 37.5 83 75 24 125 18.8 84 75 12 125 18.8 83 75 15 100 15 83 DIHW1018 DIHW1016 DIHW1026 DIHW1038 DIHW1036 DIHW1037 12 (9 ~ 18) 24 (18 ~36) 48 (36 ~75) 78 78 7 MECHANICAL DRAWING 0.60 [0.024"] 2.54 [0.100"] 23 10.50 [0.413"] Dual Output +Vin Common NC -Vout +Vout -Vin -Vin 12 15 20.3 [0.80"] 11 15.22 [0.600"] 1 24 Single Output +Vin NC -Vout +Vout NC -Vin -Vin 2.54 [0.100"] SIDE VIEW Pin 1 11 12 13 15 23 24 3.90 [0.154"] 0.20 [0.008"] 31.8 [1.25"] 13 BOTTOM VIEW CONTACT: www.delta.com.tw/dcdc USA: Europe: Asia & the rest of world: Telephone: East Coast: (888) 335 8201 West Coast: (888) 335 8208 Fax: (978) 656 3964 Email: DCDC@delta-corp.com Phone: +41 31 998 53 11 Fax: +41 31 998 53 53 Email: DCDC@delta-es.com Telephone: +886 3 4526107 ext 6220~6224 Fax: +886 3 4513485 Email: DCDC@delta.com.tw WARRANTY Delta offers a two (2) year limited warranty.
