LNK304GN Datasheet PDF - Power Integrations

This device is specifically designed to replace linear and capacitor-fed (cap dropper) non-isolated power supplies in the under 360 mA output current range. It integrates 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.

● Low cost and component count buck converter

● Fully integrated auto-restart for short-circuit and open loop fault protection

● Tight tolerances and negligible temperature variation

● Supports buck, buck-boost and flyback topologies

● Excellent line and load regulation even with typical configuration
