General Description

SD4938 is a current mode PWM controller with 150V MOSFET used for SMPS.

SD4938 integrates high-voltage start-up circuit.

It enters burst mode at light load to reduce the system standby power dissipation;

Key Features

  • various protections, including VDD undervoltage protection, VDD overvoltage protection, lead edge blanking, over current protection, over temperature protection, etc. Meanwhile, if any protection occurs, the circuit will continue to restart automatically until the system recovers. SOP-8-225-1.27.
