How to choose the MOSFET of the switching power supply, it is enough to read this!

Updated: 2022-03-17
Views: 5135

The MOSFET choice of the DC/DC switch controller is a complex process. Just considering the rated voltage and current of MOSFET is not enough to choose the appropriate MOSFET. To keep MOSFET within the specified range, a balance must be achieved between the low gate charge and the low -conducting resistance. In a multi……
