Description: Universal-Input/15 W 67 kHz Flyback Switching Regulator

Features

* 67 kHz PWM with ±5% Frequency Jittering Cost Reduction of EMI Noise Filtering
* Rugged 650 V Avalanche-Rated MOSFET Simplified Surge Absorption No VDSS Derating Required
* Low rDS(on) (3.95 Ω maximum)
* Auto-Burst Mode for Stand-By Operation or Light Loads Less Transformer Audible

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.
