1.82 V - 500 mA, 6 MHz synchronous step-down converter based on the ST1S15

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.

  • 85% typical efficiency
