SDH8322S is a current mode PWM controller with built-in high-voltage MOSFET used for SMPS.
SDH8322S 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.
SDH8322S 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.
Adjustable output voltage including: 12V, 15V and 18V
