TOP256EN

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
