Energy-Efficient CV/CC Switcher (Tight Output Regulation) for Very Low Cost Chargers and Adapters

Applications
Product Details

Description:

  • Energy-efficient replacement for regulated linear transformer and discrete power supply designs
  • Universal input range allows worldwide operation
  • Self-biased supply – saves transformer auxiliary winding and associated bias supply components
  • Built-in current limit and hysteretic thermal shutdown protection
  • Fully integrated auto-restart for short-circuit and open loop protection
  • Tight tolerances and negligible temperature variation on key parameters eases design and lowers cost
  • High maximum switching frequency allows very low ?ux density transformer designs, practically eliminating audible noise
  • Frequency jittering greatly reduces EMI
  • Packages with large creepage to high voltage pin
  • Lowest component count switcher solution

Applications:

  • Chargers for cell/cordless phones, PDAs, digital cameras, MP3/portable audio devices, shavers etc.
  • Standby and auxiliary supplies
