I built it using the exact same parts written in the schematic. ![]() Hello everyone, I made a 50Khz SMPS using the schematic I have attached to my message. So I have two identical half bridge smps, each uses two mosfets and one IR2110 which drives the mosftets, both IR2110 are powered from a single small transformer and rectifier/voltage regulator. SG5325 and IR2110 do make a good combination for an offline regulated half bridge, you don't need to use a 'dedicated half bridge driver' as DjLeco said. ![]() SG3525 is a voltage mode controller, which is right for the half-bridge topology, but typically requires type III compensation which you don't have. Circuit diagrams for the same smps pwm control output is used to drive the integrated MOSFET sg3525 ir2110. ![]() I’ve been trying to repair a 1.6A 5V SMPS.
