Features

AI Translation
  • Low thermal impedance junction-to-case (2 ℃ 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
  • 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
  • Heatsink 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
