STEVAL-ISA131V1 Datasheet, PDF (1/4 Pages) STMicroelectronics – Ultra-fast load and line transient

STEVAL-ISA131V1
1.82 V - 500 mA, 6 MHz synchronous step-down converter
based on the ST1S15
Data brief
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.
