STEVAL-ISA158V1

38 V, 2 A synchronous step-down switching regulator evaluation

board based on the A6986

Data brief

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.

Features

 4 V to 38 V operating input voltage

 Low consumption mode or low noise mode

 30 µA IQ at light load (LCM VOUT = 3.3 V)

 5 µA IQ-SHTDWN

 Adjustable fSW (250 kHz - 2 MHz)

 Output voltage adjustable from 0.85 V to VIN

 Embedded output voltage supervisor

 Synchronization

 Adjustable soft-start time

 Internal current limiting

 Overvoltage protection

 Output voltage sequencing

 Peak current mode architecture

 RDS(on)HS = 180 mΩ; RDS(on)LS = 150 mΩ

 Thermal shutdown

 RoHS compliant
