Product Overview

The LNK302GN is a lowest component count energy efficient Off-Line Switcher IC specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360mA output current range while offering much higher performance and energy efficiency. LinkSwitch-TN devices integrate a 700V power MOSFET, oscillator, simple ON/OFF control scheme and a high voltage switched current source, frequency jittering, cycle-by-cycle current limit and thermal shutdown circuitry onto a monolithic IC. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias supply and associated circuitry in buck or flyback converters.
  • Supports buck, buck-boost and flyback topologies
  • Excellent line and load regulation even with typical configuration
  • High bandwidth provides fast turn-ON with no over-shoot
  • Current limit operation rejects line ripple
  • Universal input voltage range
  • Built-in current limit and hysteretic thermal protection
  • Higher efficiency than passive solutions
  • Higher power factor than capacitor-fed solutions
  • Entirely manufacturable in SMD
