- Quasi-Resonant (QR) mode operation: Valley turn on of the primary MOSFET to achieve low switching losses
- Output current is monitored by primary detection for reliable Over Current Protection and Short Circuit Protection
- PWM/PFM control for higher average efficiency
- Burst mode control for low no load loss and efficiency
- HV start up circuit is used to reduce no-load
- Internal high current MOSFET driver: 120mA
- Auto-Recovery for OVP/OCP/SCP/OTP
- Maximum frequency limitation 125kHz
- Compact package: SO8
