LM2596 Adjustable DC-DC Converter Step Down Buck Regulator


5 in stock

SKU: LM2596 DC-DC Stepdown Converter Category:


Step down buck power supply based on the LM2596 IC.

The LM2596-based step down voltage regulator board is a low-ripple adjustable output voltage power supply capable of providing up to 3A of continuous current (2A without a heat-sink).

This DC to DC Step Down Regulator has a high conversion efficiency of up to
92%, the higher the Output voltage the higher the efficiency.

Wide input voltage from 4.75v to 23v and an adjustable voltage from 1v to 17v, input voltage must be >1.5v higher than the output voltage.

Ideal for battery operated projects requiring an efficient regulated power supply.
