Product Overview

LinkSwitch™-TN 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. LinkSwitch-TN devices 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.
  • Lowest cost and component count buck converter solution
  • Fully integrated auto-restart for short-circuit and open loop fault protection – saves external component costs
  • LNK302 uses a simplified controller without auto-restart for very low system cost
  • 66kHz operation with accurate current limit – allows low cost off-the-shelf 1 mH inductor for up to 120 mA output current
  • Tight tolerances and negligible temperature variation
  • High breakdown voltage of 700 V provides excellent input surge withstand
  • Frequency jittering dramatically reduces EMI (~10 dB)
  • Supports buck, buck-boost and flyback topologies
  • System level thermal overload, output short-circuit and open control loop protection
  • 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 (85VAC to 265VAC)
