  • The A5972D is a step-down monolithic power switching regulator with a minimum switch current limit of 1.8 A so it is able to deliver up to 1.5 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to VIN.

    The device uses an internal P-channel DMOS transistor (with a typical RDS(on)of 250 mΩ) as a switching element to minimize the size of the external components.
    An internal oscillator fixes the switching frequency at 250 kHz. Having a minimum input voltage of 4 V only it fits the automotive applications requiring the device operation even in cold crank conditions. A pulse-by-pulse current limit with the internal frequency modulation offers an effective constant current short-circuit protection.

    主要特性

    • Qualified following the AEC-Q100 requirements (see PPAP for more details)
    • 1.5 A DC output current
    • Operating input voltage from 4 V to 36 V
    • 3.3 V / (± 2%) reference voltage
    • Output voltage adjustable from 1.235 V to VIN
    • Low dropout operation: 100% duty cycle
    • 250 kHz internally fixed frequency
    • Voltage feedforward
    • Zero load current operation
    • Internal current limiting
    • Inhibit for zero current consumption
    • Protection against feedback disconnection
    • Thermal shutdown
