SD4938TR Switching Voltage Regulators Silan SOP-8

SD4938TR Switching Voltage Regulators Silan SOP-8 is a current mode PWM controller with 150V MOSFET used for SMPS.

SD4938TR integrates high-voltage start-up circuit. It enters burst mode at light load to reduce the system standby power dissipation; the frequency reduction function optimizes the conversion efficiency at light load; the soft startup function reduces the stress of device to avoid transformer saturation.

SD4938TR 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.
