STEVAL-ISA039V1

Single phase 5A step-down converter evaluation board

based on L6727

Features

customizable by changing resistor

Description

The purpose of this design is to demonstrate the

key features of STMicroelectronics L6727 a new

powerful buck controller. The L6727 allow simple,

cost effective design of complete step-down

voltage regulators. Indeed it provides a full

solution by integrating a 0.8V reference, control

logic and protection, and NMOS drivers in an 8-

pin package. L6727 demo 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 5V to 12V buses and the output

voltage is fixed at 1.25V. The application can

deliver an output current in excess of 5A. The

switching frequency is 300 kHz.
