Utsource electronic components LNK304PN


Utsource electronic components LNK304PN picture
1. Description
LinkSwitch-TN is specifi cally 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 startup 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.
2. Features
> 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
