  • The STEVAL-ISA098V1 demonstration board is a step-down switching power supply based on the L7985A in HSOP8 package.

    The L7985A is a step-down regulator with a 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.
    The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN.
    Requiring a minimum set of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz.

    Key Features

    • 2 A DC output current
    • From 4.5 V to 38 V range input voltage
    • Output voltage adjustable from 0.6 V
    • 250 kHz switching frequency programmable up to 1 MHz
    • Internal soft-start and enable
    • Low dropout operation: 100% duty cycle
    • Voltage feed-forward
    • Zero load current operation
    • Overcurrent and thermal protection
    • RoHS compliant
