A low ac-impedance input source is recommended. An input filter between input source and DC/DC power modules is recommended, please refer to the Figure 9. Layout and EMC Considerations Delta’s DC/DC power modules are designed to operate in a wide variety of systems and applications. For design assistance with EMC compliance and related PWB layout issues, please contact Delta’s technical support team. An external input filter module is available for easier EMC compliance design. Application notes to assist designers in addressing these issues are pending release. The Over-Temperature Protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature threshold , the modules will shut down, and enter the auto-restart mode. . For auto-restart mode, the module will monitor the module temperature after shutdown. Once the temperature of module is decreased by an OTP hysteresis, the module will restart. Remote On/Off The remote on/off feature on the module can be either negative or positive logic depend on the part number options on the last page. Soldering and Cleaning Considerations 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. For Negative logic version, turns the module on during a external logic low and off during a logic high. If the remote on/off feature is not used, please short the on/off pin to Vi (-). For Postive logic version, turns the modules on during a external logic high and off during a logic low. If the remote on/off feature is not used, please leave the on/off pin to floating. Remote on/off can be controlled by an external switch between the on/off terminal and the Vi (-) terminal. The switch can be an open collector or open drain. The DC level on/off signal is suggested. FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will 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 1s. The modules will try to restart after shutdown. If the overload condition still exists, the module will shut down again. This restart trial will continue until the overload condition is corrected.

To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. (WITH HEAT SPREADER) Thermal Testing Setup The following figure shows the thermal test setup. The power module is mounted on a test PWB in a sealed enclosure and the heat spreader top side is attached to a clod plate with thermal interface material. Cold Plate TIM Heat Spreader Figure 17: Hot spot's temperature measurement location The allowed maximum hot spot on heat spreader temperature is defined at 70℃. PWB Module Figure 16: Thermal test setup Thermal Derating 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.
