Other Parts Discussed in Thread: TPS51367

Hi,

If we don't need the LP# function of TPS51367,

Can the LP# pin tied to the VREF directly for disabling it?

Thanks

    Hi, Mr. Go,

    When the IC is enabled, LP# pin outputs 1uA current. If LP# is connected VREF, VREF output current is decreased by 1uA. As long as that reduction does not affect any other characteristics such as REFIN voltage, you can connect VREF to LP# pin to disable LP mode.

    Best regards,
