      SDH8303
      CURRENT MODE PWM CONTROLLER

      SDH8303 is a current mode PWM controller with built-in high-voltage MOSFET used for SMPS.

      SDH8303 has a built-in high-voltage startup function. 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; frequency jitter improves EMI performance; the soft startup function reduces the device stress to avoid transformer saturation. 

      SDH8303 integrates complete protections, including VDD undervoltage protection, VDD overvoltage protection, lead edge blanking, output short-circuit protection, over current protection, over temperature protection, etc.
