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
