Features
• Works across universal AC mains input from 85 VAC to 265 VAC
• Low-side gate driver to drive primary side FET
• A logic-level gate driver to control external high-side floating gate driver IC (ACF)
• Free-running oscillator with PWM generator for start-up
• Line under voltage protection (UVP) and line overvoltage protection (OVP)
• Secondary overvoltage protection via auxiliary winding (SOVP)
• Overcurrent protection (OCP)
• Short-circuit protection (SCP)
• VCC pin short protection (VCCPSP)
• Integrated VCC boost switch to support varied output voltage without the need for an external regulated LDO
• Integrated high-voltage start-up and shunt regulator
• A novel dual-output PET receiver is used to drive both high/low side switch using a single PET
