      SDH8312
      NON-ISOLATED AC TO DC CONTROLLER

          SDH8312 is AC-DC controller with built-in 650V MOSFET used for SMPS.

          SDH8312 integrates high-voltage circuit and self-power function for fast startup and low standby power dissipation. It features the frequency reduction function to optimize the conversion efficiency at light load; the soft startup function reduces the device stress to avoid transformer saturation. 

          SDH8312 integrates various protections, including VDD undervoltage protection, open loop protection, output overload protection, output short-circuit protection, over temperature protection, etc. Meanwhile, if any protection occurs, the circuit will continue to restart automatically until the system recovers.
