STEVAL-ISA026V1: 3.3V @ 20A, 4.5 ~ 14V in

Summary

This 4-layer PCB evaluation board implements a step-down DC-DC converter and demonstrates the operation of the L6732 device in a general purpose application. The input voltage can range from 4.5 V to 14 V with an output voltage of 3.3 V.

The module can deliver an output current in excess of 20 A. The switching frequency is initially set at 250 kHz (controller free-running FSW), but a 500 kHz switching frequency can also be selected.
