  • Based on the ST1S41 step-down switching regulator, the STEVAL-ISA108V1 demonstration board is an internally-compensated 850 kHz fixed-frequency PWM synchronous step-down converter.

    The ST1S41 operates from 4.0 V to 18 V input, while it regulates an output voltage as low as 0.8 V and up to VIN(100% duty cycle).
    The ST1S41 integrates a 95 mΩ high side switch and 69 mΩ low side synchronous rectifier, resulting in very high efficiency with very low output voltages.
    The peak current mode control with internal compensation offers a compact solution with a minimum component count.

    Key Features

    • 4 to 18 V input voltage
    • Output voltage adjustable from 0.8 V
    • 850 kHz switching frequency
    • Internal soft-start
    • Integrated 95 mΩ and 69 mΩ power MOSFETs
    • All ceramic capacitor
    • Enable function
    • Cycle-by-cycle current limiting
    • Current fold-back short-circuit protection
    • RoHS compliant
