【Electric Competition】LM2576-Step-down DCDC

Overview

The AR7 selected for actual measurement is 13k, AR8 is 3k, the potentiometer is 20k, and the voltage reduction range is 3V-VIN.

The LM2576 series voltage regulator is a very simple and convenient step-down design switching regulator;

Actual measurement can meet the power supply needs of most ordinary motors and power amplifiers;

To be honest, the power chips starting with LM from TI are quite good. Although they are a little expensive, they are very useful.
