TOP412 Datasheet (Power Integrations Inc.) - Three-terminal DC to DC PWM Switch

TOP412, Three-terminal DC to DC PWM Switch

The TOPSwitch family implements, with only three terminals, all functions necessary for a DC to DC, converter: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated 120 kHz oscillator, high voltage start-up bias circuit, bandgap derived

TOP412/414 TOPSwitch Family Three-terminal DC to DC PWM Switch Product Highlights Low Cost Replacement for Discrete Switchers Up to 15 fewer components - cuts cost, increases reliability Allows for a smaller and lighter solution under 12 mm height, all surface mount components Over 80% Efficiency in Flyback Topology Built-in start-up and current limit reduce DC losses Low capacitance MOSFET cuts switching losses CMOS controller/gate driver consum
