The internal power MOSFETs source is connected to the SOURCE (S) pin.ġ2V /120 switch mode power supply circuitThe circuit diagram of a practical 12V/120mA transformerless switch mode power supply is shown above. A current above than 49uA delivered to this pin will inhibit the switching. FEEDBACK (FB) pin controls the switching of the built in power MOSFET. The external by pass capacitor (0.1uF) is connected to the BYPASS (BP) terminal. Drain (D) pin the drain connection of the built in power MOSFET. The pin configuration and the typical application diagram of LNK304 are shown above. In general the LNK304 has a better performance when compared to the many other discrete buck regulators.LNK304 pin configuration and typical application Other features of LNK304 includes low temperature variation, thermal shut down,high break down voltage, good line & load regulation, high band width, wide input voltage range (85 to 230V AC) etc. The IC has a built in auto start circuit for short circuit and open loop fault protection. Applications of a power supply based on this IC includes hand held devices, timers, small appliances, LED drivers, industrial gadgets etc.LNK304 is a low component count, efficient off-line switcher IC that can support buck, buck-boost and flyback topologies. The circuit shown below is of a 12V/120mA output, 85 to 230V AC input transformerless switch mode power supply using LNK304 IC.

Transformer less switch mode power supplies have become very popular these days.
