Description
The STEVAL-ISA131V3 is a product evaluation board designed around the ST1S15, a highefficiency miniaturized step-down converter able to provide 500 mA output current from an input voltage of 2.3 V to 5.5 V. The converter operates at a switching frequency of 6 MHz and is specifically designed for applications where high efficiency and small application areas are key factors.
