Switching power supply driver PM4040F in the small and medium power half-bridge circuit application as shown below: using PM4040F to drive a 200W to 800W switching power supply can refer to the following circuit diagram, other circuit parts please PM4040F practical circuit. If the power supply scheme is less than 1000W, the drive output group that is not used can be suspended by the method of the circuit to reduce the DC supply current of the driver by half. The driving capability here is that it can directly drive 100A IGBT tubes or 60A MOS tubes, and it is fully qualified to handle 1000W power supply.
