STEVAL-ISA038V1: 1.25V @ 5A, 5 ~ 12V in

Summary

This evaluation board is based on L6728, a single-phase step-down controller with integrated high-current drivers that provides complete control logic and protection to realize in a simple way general DC-DC converters by using a compact VFQFPN-10 package.

The board realizes in a two-layer PCB a step-down DC-DC converter and shows the operation of the device in a general-purpose low-current application.
