Overview

This high efficiency 3 A DC-DC step down regulator can connect to car battery without the need for switching and also it can connect to cigarette lighter line or  ACC power line.

This product is a useful low voltage source for lower voltages, starting from higher voltages. The range of input voltages is quite varied, being compatible with most accumulators or power supplies. Also, the output voltage is quite varied and the maximum voltage can be set by sticking back two pads for the desired voltage.

The voltage source works in switching at a fairly high frequency of 500 kHz, so it has small dimensions and very good efficiency. It can be integrated into your small, innovative projects and does not require additional heat dissipation for a maximum current of 2.1A.
