LNK304PN 概述

LinkSwitch-TN is specifi cally designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at equal system cost while offering much higher performance and energy effi ciency.®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 and associated circuitry in buck or fl yback converters. The fully integrated auto-restart circuit in the LNK304-306 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.

LNK304PN Much Higher Performance over Discrete Buck and Passive Solutions

• Supports buck, buck-boost and fl yback topologies

• System level thermal overload, output short-circuit and open control loop protection

• Excellent line and load regulation even with typical confi guration

• 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 effi ciency than passive solutions

• Higher power factor than capacitor-fed solutions

• Entirely manufacturable in SMD

LNK304PN Applications

• Appliances and timers

• LED drivers and industrial controls
