Information

TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device

Key Features

  • Output Power - Adapter : 30 W
  • Output Power - Open Frame : 62 W
  • Lower System Cost, Higher Design Flexibility
  • Multi-mode operation maximizes efficiency at all loads
  • New eSIP-7F and eSIP-7C packages
  • 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
  • Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications
  • Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink
  • No heat sink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC
  • Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
  • Allows both primary and secondary sensing
  • Line undervoltage (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
  • 132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
  • Half frequency option for video applications
  • Frequency jittering reduces EMI filter cost
  • Heat sink is connected to SOURCE for low EMI
  • Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
  • Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset
  • Fully integrated soft-start for minimum start-up stress
  • Extended creepage between DRAIN and all other pins improves field reliability
