The IC component lNK304PN is a step-down converter IC. Features Fully integrated auto-restart for short-circuit and open-loop fault protection 66KHz operation with precise current limiting Tight tolerances and negligible temperature fluctuations High breakdown voltage of 700V Frequency jitter significantly reduces electromagnetic interference (10dB) Integrated current limiting and hysteresis over-temperature protection High thermal shutdown temperature ( min. +135 °C)

LNK304PN - this device is specifically designed to replace linear and capacitive-fed (capacitor power supply) non-isolated power supplies with output currents below 360mA. It features a 700V power MOSFET, oscillator, simple on/off control, high voltage switched power source, frequency jitter, cycle current limit and overheat protection.
