Enhanced, Energy-Efficient, Off-Line Switcher IC with Super Peak Power Performance

Filters Filter Products


  • Simple ON/OFF control, no loop compensation needed
  • Delivers peak power of up to 3 times maximum continuous output power
  • 277 kHz operation during peak power significantly reduces transformer size
  • Tight I2f tolerances and negligible temperature variation of key parameters ease design and lower cost
  • Adaptive on-time extension increases low line peak output power and minimizes bulk capacitor size
  • Programmable smart AC line sensing provides latching shutdown during short circuit, overload and open loop faults and prevents ON/OFF glitches during power down or brownout


Ideal for applications with large peak to continuous load ratio requirements

  • Inkjet printer
  • Data storage
  • Audio amplifier
  • DC motor drives
