This document is a data brief for an evaluation board of a single-phase 5A step-down PWM controller by STMicroelectronics. The evaluation board is based on the L6728, a controller with integrated high-current drivers that provides complete control logic and protection for general DC-DC converters. The board demonstrates the operation of the device in a general-purpose low-current application. The input voltage range is 5V to 12V, the output voltage is fixed at 1.25V, and the output current can exceed 5A. The switching frequency is 300kHz.
The STEVAL-ISA038V1 is a single-phase step-down evaluation board designed for general DC-DC converter applications. It is based on the L6728, a PWM controller featuring integrated high-current drivers in a compact VFQFPN-10 package. The board demonstrates the operation of the device in a two-layer PCB configuration suitable for low-current applications.
