TOP256 datasheet



The TOP256 is Integrated Off-Line Switcher with Advanced Feature Set and Extended Power Range.

TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.


1. Lower System Cost, Higher Design Flexibility

• Multi-mode operation maximizes efficiency at all loads

• New eSIP-7F and eSIP-7C packages

• Low thermal impedance junction-to-case (2 °C per watt)

• Low height is ideal for adapters where space is limited

• Simple mounting using a clip to aid low cost manufacturing

• Horizontal eSIP-7F package ideal for ultra low height adapte and monitor applications

• Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink

• No heat sink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC
