Can LM5176 work in constant current mode?

Will keep same current output but decrease the output voltage?

Thank You

    Hello Minki,

    Thanks for reaching out to us via e2e.

    As described in the datasheet, section 7.3.6 Average Input/Output Current Limiting:

    The LM5176 provides optional average current limiting capability to limit ... the output current of the DC/DC converter.
    If the voltage drop across the sense resistor is greater than 50 mV, ... the output voltage of the converter decreases to limit the ... output current.
    The average current limiting feature can be used in applications requiring a regulated current ... into the load.

    Best regards,
    Harry
