Description

The STEVAL-ISA158V1 is a product evaluation

board based on ST's A6986, a 38 V, 2 A

synchronous step-down switching regulator with

30 µA of quiescent current. It is designed for

automotive system battery-powered applications.

It can be used in low consumption mode (LCM)

such as in car body implementations, or in low

noise mode (LNM) such as in car audio

applications.
