A low ac-impedance input source is recommended. If the source inductance is more than a few μH, we advise 33μF-100μF electrolytic capacitor (ESR < 0.7Ω at 100kHz) mounted close to the input of the module to improve the stability. Safety Considerations The power module must be installed in compliance with the spacing and separation requirements of the end-user’s safety agency standard, i.e., IEC 62368-1, UL60950-1, CSA C22.2 NO. 60950-1 2nd and IEC 60950-1 2nd: 2005 and EN 609501 2nd: 2006+A11+A1: 2010, if the system in which the power module is to be used must meet safety agency requirements. 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 fastacting fuse with 20A maximum rating to be installed in the ungrounded 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 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.

If the output current exceeds the OCP set point, the modules will shut down (hiccup mode). The power module provides an optional open-drain PGOOD signal which indicates if the output voltage is being regulated. When the module is power on, but output voltage is more than +/-5 from the expect voltage set point due to input under voltage, over temperature, over load, or out of control, the power good signal will be pulling low. A 10 kΩ pull-up resistor is recommended to 3.3V source. If the power good feature is not used, this pin should be left open. 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. 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. 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 maximum allowable leakage current of the switch is 10uA. The switch must be capable of maintaining a low signal Vo/off
