STEVAL-ISA158V1:38 V - 2 A synchronous step-down switching regulator evaluation board based on the A6986

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.

Key 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
