This document is a datasheet of the STEVAL-ISA044V5, which is a demonstration board based on the ST1S10 device assembled in a Power SO-8 ePad package.
The STEVAL-ISA044V5 is a demonstration board designed for evaluation purposes, based on the ST1S10 device assembled in a Power SO-8 ePad package. This step-down DC-DC converter provides up to 3 A of output current over an input voltage range of 2.5 V to 18.0 V. It is optimized for powering high voltages in LCD applications and low voltages in digital-core HDD applications, replacing high-current linear solutions when power dissipation is a concern.
