Sales Briefcase
  • The STEVAL-ISA160V1 evaluation board is based on the AST1S31HF internally compensated 2.3 MHz fixed-frequency PWM synchronous step-down regulator.

    The device operates on a 2.8 V to 4.0 V input voltage and provides a regulated output voltage from as low as 0.8 V up to Vin.
    The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.
    All the components on the evaluation board are automotive grade.

    Key Features

    • AECQ100 qualification
    • 3 A DC output current
    • 2.8 V to 4 V input voltage
    • Output voltage adjustable from 0.8 V
    • 2.3 MHz switching frequency
    • Internal soft-start and enable
    • Integrated 70 mΩ and 55 mΩ power MOSFETs
    • All ceramic capacitor
    • Power good (POR)
    • Cycle by cycle current limiting
    • Current fold back short circuit protection
    • VFDFPN 3x3 - 8L package
    • RoHS compliant
