Other Parts Discussed in Thread: DRV10975

Hi there,


if I don't use the included step-down regulator of the DRV10975 driver, should I let the leave the pins VREG, SW and SWGND floating?  Or which minimum wiring would you recommend?

Thanks for your help,
Johannes

    Hi Johannes,

    Regulator is use to power internally circuitry as well, so step down regulator needs to be configured in Linear/Buck regulator mode.  Since resistive energy is lost in linear regulator; Buck regulator is  more efficient compared to Linear Regulator.
