Description

The STEVAL-ISA131V1 is a product evaluation

board designed around the ST1S15, a high

efficiency miniaturized step-down converter

capable to providing 500 mA of output current

from an input voltage from 2.3 V to 5.5 V.

This converter works at a 6 MHz switching

frequency and is specifically designed for

applications where high efficiency and small

application area are key factors.
