The TOP255EN is an enhanced EcoSmart�, Integrated Off-line Switcher with 25W 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
