TOP254EN General Description

Converter Offline Flyback Topology 66kHz, 132kHz eSIP-7C

Key Features

  • Multi-mode operation maximizes efficiency at all loads
  • Low thermal impedance junction-to-case
  • Low height is ideal for adapters where space is limited
  • Simple mounting using a clip to aid low manufacturing
  • Output overvoltage protection is user programmable for latching/non-latching shutdown with AC reset
  • Allows both primary and secondary sensing
  • Line undervoltage detection prevents turn-OFF glitches
  • Line overvoltage shutdown extends line surge limit
  • Accurate programmable current limit
  • Optimized line feed-forward for line ripple rejection
  • Frequency jittering reduces EMI filter
  • Heat sink is connected to SOURCE for low EMI
  • 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
  • Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
  • 132kHz Frequency reduces transformer and power supply size
