DI-139, LNK304DN, High Efficiency, Dual Output Buck Converter

DI-139, Reference Design for LNK304DN, The power supply is implemented using a simple buck topology that allows for two output voltages without the need for a transformer. Typical applications include metering power supplies, Where a 3.3V supply is required for metrology and a 12V supply is required to switch on and off relays or power a radio for remote meter reading
