  • The STEVAL-ISA083V1, based on the ST1S40IPUR, is an internally compensated 800 kHz fixed-frequency PWM synchronous step-down converter demonstration board.

    The ST1S40 operates from 4.0 V to 18.0 V input, while it regulates an output voltage as low as 0.8 V and up to VIN(100% duty cycle).
    The ST1S40 integrates a 95 mΩ high-side switch and a 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltage.
    The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.
    The ST1S40 is protected through cycle-by-cycle current limiting in case of overload and is also protected by a current foldback function with frequency reduction in case of short-circuit.
    The device is available with an enable on/off function.

    主な特徴

    • Input voltage Vin: 4 V to 18 V
    • Output voltage Vout : 3.3 V
    • Maximum output current: 4 A
    • Switching frequency: 800 kHz
    • Short-circuit protected
    • RoHS compliant
