Features
• 800 V avalanche-rugged power MOSFET allowing ultra wide range input VAC to be achieved
• Embedded HV start-up and senseFET • Built-in soft-start • Quasi-resonant current mode PWM controller with drain current limit (IDlim) • Multifunction ZCD pin:
– Zero-current detection – OCP threshold (IDlim) setup – Output OVP (auto-restart) – Feed-forward compensation • Support isolated flyback topology with optocoupler • Frequency limit: – 136 kHz (L type), 225 kHz (H type) • Less than 30 mW @ 230 VAC in no-load condition • Brown-out set through resistor divider • Short-circuit protection (auto-restart) • Hysteretic thermal shutdown
Application
• Auxiliary p
