Description

This evaluation board demonstrates the key

features of STMicroelectronics’ L6727, a new

powerful new buck controller. The L6727 makes

the design of complete step-down voltage

regulators simple and cost effective. It provides a

full solution by integrating a 0.8 V reference,

control logic and protection, and NMOS drivers in

an 8-pin package. The L6727 evaluation board

implements a step-down DC/DC converter in a

four-layer PCB and demonstrates the operation of

the device in a general-purpose application. The

input voltage can range from 5 V to 12 V and the

output voltage is fixed at 1.25 V. The application

can deliver an output current up to 20 A. Airflow

must be applied with current higher than 18 A
