LNK306PN LNK306P OFF LINE SWITCHER IC DIP-8B

Lowest Component Count, Energy Efficient Off-Line Switcher IC

 

Product Highlights

·          Cost Effective Linear/Cap Dropper Replacement

·          Lowest cost and component count buck converter solution

·          Fully integrated auto-restart for short-circuit and open loop fault protection - saves external component costs

·          66 kHz operation with accurate current limit - allows low cost off-the-shelf 1mH inductor for up to 120mA 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) - minimizes EMI filter cost

·          High thermal shutdown temperature (+135°C minimum)

 

Much Higher Performance over Discrete Buck and Passive Solutions

·          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 (85 VAC to 265 VAC)

·          Built-in current limit and hysteretic thermal protection

·          Higher efficiency than passive solutions

·          Higher power factor than capacitor-fed solutions

·          Entirely manufacturable in SMD

 

EcoSmart® – Extremely Energy Efficient

·          Consumes typically only 50/80mW in self-powered buck topology at 115/230 VAC input with no load (opto feedback)

·          Consumes typically only 7/12mW in flyback topology with external bias at 115/230 VAC input with no load

·          Meets Blue Angel, Energy Star, and EU requirements

Description

LinkSwitch-TNis 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 700 V 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 an associated circuitry in buck or flyback converters. The fully integrated auto-restart circuit safely limits output power during fault conditions such as short-circuit or open loop, reducing component count and system-level load protection cost. A local supply provided by the IC allows use of a non-safety graded optocoupler acting as a level shifter to further enhance line and load regulation performance in buck and buck-boost converters, if required
