  • The ST1S41 is an internally compensated 850 kHz fixed-frequency PWM synchronous step-down regulator. 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.

    The ST1S41 integrates 95 mΩ high-side switch and 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltages.
    The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.
    The ST1S41 is available in VFQFPN 4 mm x 4 mm 8-lead package and HSOP-8.

    主要特性

    • 4 A output current
    • 4.0 V 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
    • Cycle-by-cycle current limiting
    • Current foldback short-circuit protection
    • VFQFPN 4x4-8L and HSOP-8 packages
