Product overview

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.

  • All features

    • 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
