STEVAL-ISA038V1

Single phase 5 A step-down based on PWM controller

evaluation board based on the Power Good L6728

Features

Description

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.

The input voltage can range from 5 V to 12 V

buses and the output voltage is fixed at 1.25 V.

The application can deliver an output current in

excess of 5 A.

The switching frequency is 300 KHz.
