Schematic diagram of output switching regulator power supply based on LM2676

The LM2676 is a switching-type integrated voltage regulator that provides all the functions of a switching regulator with a drive capability of up to 3 A and step-down, with good linearity and load regulation: using a low on-resistance The DMOS power switch achieves high output efficiency; it has a fixed output of 3.3 V, 5 V and 12 V, or regulated output.

The following figure is the LM2676, composed of 8V to 40V input, 5V, 3A output DC regulated power supply circuit
