Product Overview

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
