Features
* 67 kHz PWM with ±5% frequency jittering for EMI noise filtering and cost reduction Rugged 650 V avalanche-rated MOSFET:
* Simplified surge absorption
* No VDSS derating required Low RDS(on) : 2.8 Ω maximum Auto-burst mode for stand-by operation or light loads; less transformer audibl
Applications
* from DVD players and VCR player/recorders to ac adapters for cellular phones and digital cameras. An auto-burst standby function reduces power consumption at light load, while multiple protections, including the avalanche-energy guaranteed MOSFET, provide high reliability of system design.
