POWER INTEGRATIONS TOP256EN Datasheet & Stock

The TOP256EN is an enhanced EcoSmart™, Integrated Off-line Switcher with 30W peak, advanced feature set and extended power range. TOPSwitch-HX cost effectively incorporates a 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.




Multi-mode operation maximizes efficiency at all loads

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

Line under-voltage (UV) detection prevents turn-off glitches

Line overvoltage (OV) shutdown extends line surge limit

Accurate programmable current limit

Optimized line feed-forward for line ripple rejection

Half frequency option for video applications

Frequency jittering reduces EMI filter cost





Heat sink is connected to SOURCE for low EMI

Fully integrated soft-start for minimum start-up stress

Energy efficient over entire load range

Less than 200mW at 230VAC, no load consumption

Standby power for 1W input
