STEVAL-ISA028V1: 1.25V @ 20A, 5 ~ 12V in

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 (@VIN = 5 V). The switching frequency is 300 kHz.
