Description

STEVAL-ISA131V2 is an evaluation board

designed around the ST1S15, a high efficiency

miniaturized step-down converter able to provide

500 mA output current from an input voltage of

2.3 V to 5.5 V. This converter working at 6 MHz

switching frequency and is specifically designed

for applications where high efficiency and small

application area are the key factors.
