LNK305PN - Brand New Power Integrations AC DC Converters, Offline Switchers
-
Description
The LNK305PN is an AC DC converter offline switcher that is specifically designed to replace all linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range at an equal system cost while offering much higher performance and energy efficiency. The LNK305PN integrates 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 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 the 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.
