SDH8321H is a current mode PWM controller with built-in 820V MOSFET used for SMPS.
SDH8321H integrates high-voltage startup 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 can reduce the stress of device and avoid transformer saturation.
SDH8321H features various protections, including VDD undervoltage protection, VDD overvoltage protection, lead edge blanking, over current protecting, over temperature protection, etc. Meanwhile, if any protection occurs, the circuit will continue to restart automatically until the system recovers.
