1.2V-32V @3A Variable Switching Regulator

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 switching regulator is much higher than the linear regulators. The input voltage for this circuit is 8V-35V
and it can produce the output of 1.8V to 32V, that can be varied by using potentiometer R3.

Features

• Input(V): 8VDC to 35VDC
• Output(V): 1.8VDC to 32VDC
• Output load: 3A
• PCB:68mm X 50mm

Notes

• The real components are not same as shown in the 3D preview.
