Description

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
