Hi BU,

If I want to use LM5143 2nd channel for 6V (minimum) input voltage and 5V/15A output, is there any concern or special take care portion or risk?

Please advise.

    Hello Tiger

    The device may enter dropout mode at 2MHz. And both line and load transient performances of the converter are significantly reduced in this mode of operation, comparing with PWM mode.  Please run at 400kHz in order to stay in the PWM mode.
