Features
AND BENEFITS 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 audible noise Built-in leading edge blanking Soft start and low start-up current; start-up circuit disabled in operation Auto-burst stand-by (intermittent operation) input power <0.1 W at no...
