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 load
Built-in constant-voltage/constant current (CV/CC)
Multiple protections:
• Pulse-by-pulse overcurrent protection (OCP)
• Overload protection (OLP) with auto restart
• Latching overvoltage protection (OVP)
• Undervoltage lockout (UVLO) with hysteresis
• Latching thermal shutdown (TSD)
