1.2V-32V @3A Variable Switching Regulator using LM317
The circuit presented here is based on LM317. Generally, LM317 is known as a linear regulator IC, but here the circuit operates as a switching regulator. This circuit operates by transferring energy from the input to the output by using a solid state switch. Power Efficiency of a...
