Sales Briefcase
  • The STEVAL-ISA069V1 demonstration board is based on the ST1S31, which is an internally compensated 1.5 MHz fixed-frequency PWM synchronous step-down regulator. This device operates from 2.8 V to 5.5 V input, while it regulates an output voltage as low as 0.8 V and up to Vin.

    The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.

    Key Features

    • 4 A peak output current
    • From 2.8 V to 5.5 V input voltage
    • Output voltage adjustable from 0.8 V
    • 1.5 MHz switching frequency
    • Internal soft-start and enable
    • Integrated 60 mΩ and 45 mΩ power MOSFETs
    • All ceramic capacitors
    • Power Good (POR)
    • Cycle-by-cycle current limiting
    • Current foldback short-circuit protection
    • RoHS compliant
