Product Highlights
Low Cost Replacement for Discrete Switchers • 20 to 50 fewer components - cuts cost, increases reliability • Source-connected tab and Controlled MOSFET turn-on
reduce EMI and EMI filter costs • Allows for a 50% smaller and lighter solution • Cost competitive with linears above 5 W
Up to 90% Efficiency in Flyback Topology • Built-in start-up and current limit reduce DC losses • Low capacitance 700 V MOSFET cuts AC losses • CMOS controller/gate driver consumes only 6 mW • 70% maximum duty cycle minimizes conduction losses
Simplifies Design - Reduces Time to Market • Supported by many reference design boards • Integrated PWM Controller and 700 V MOSFET in a
industry standard three pin TO-220 package • Only one external capacitor needed for compensation,
bypass and start-up/auto-restart functions
System Level Fault Protection Features • Auto-restart and cycle by cycle current l.
