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. STEVAL-ISA131V1
