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)
