Product Details


Optimized for Lowest System Cost

  • Proprietary IC trimming and transformer construction techniques enable Clampless™ designs with LNK362 for lower system cost, component count and higher efficiency
  • Fully integrated auto-restart for short circuit and open loop protection
  • Self-biased supply – saves transformer auxiliary winding and associated bias supply components
  • Frequency jittering greatly reduces EMI
  • Meets HV creepage requirements between DRAIN and all other pins both on the PCB and at the package

Richer Feature Set than Linear/RCC

  • Accurate hysteretic thermal shutdown protection – automatic recovery improves field reliability
  • Universal input range allows worldwide operation
  • Simple ON/OFF control, no loop compensation needed
  • Eliminates bias winding – simpler, lower cost transformer
  • Very low component count – higher reliability and single side printed circuit board
  • Auto-restart reduces delivered power by 95% during short circuit and open loop fault conditions
  • High bandwidth provides fast turn on with no overshoot and excellent transient load response


  • Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio players, and shavers
  • Supplies for appliances, industrial systems, and metering
