STEVAL-ISA028V1
Single Phase Step-Down converter based on L6727

This design demonstrates the key features of STMicroelectronics’ L6727, a new powerful 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 demo board implements a step-down DC/DC converter in a four-layer PCB and shows 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.
