Product Overview

The LNK306DN is a LinkSwitch-TN lowest component count, Energy-efficient Off-line Switcher IC. It is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360mA output current range at equal system cost while offering much higher performance and energy efficiency. This device integrate a 700V power MOSFET, oscillator, simple on/off control scheme, 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. The fully integrated auto-restart circuit in the safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost.
  • Lowest component count buck converter solution
  • Uses a simplified controller without auto-restart
  • Tight tolerances and negligible temperature variation
  • Supports buck, buck-boost and flyback topologies
  • Excellent line and load regulation even with typical configuration
  • High bandwidth provides fast turn-on with no overshoot
  • Current limit operation rejects line ripple
  • Universal input voltage range (85 to 265VAC)
  • Built-in current limit and hysteretic thermal protection
  • Higher efficiency than passive solutions
  • Higher power factor than capacitor-fed solutions
  • Entirely manufacturable in SMD
