Description

The STEVAL-ISA158V1 is a product evaluation board based on STs 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.
