12 A Low Ripple Adjustable Step-Down DC-DC Converter

Overview

This product is a step-down voltage source with a medium power which can provide voltages between 1.25 V and 30 V, starting from 4.5 V voltage to 30 V.

It uses high-quality capacitors and has a low output ripple, making it suitable for precision applications. With this circuit, you can build your own lab controllable voltage source. All you need is a source of fixed voltage at 30 V DC maximum.

The only condition is to bear the amperage required. You can also include this module in any project of your own because it is very small and easy to mount.
