Isolated DC-DC Converter Design Considerations Slide 14

During start up, the DC/DC converter needs to provide extra current to charge up the load capacitor on customer’s board. If the maximum capacitor used in customer’s board is larger than the maximum capacitance specified by the data sheet, the DC/DC converter may fail to start due to trigging converter’s over current protection. Please check the data sheet for maximum capacitance value when selecting a DC/DC power module.
