Hi team,

In related question, it is said no issue to use by OR-ing circuit with a Schottky diode.

related question : e2e.ti.com/.../3356514

Is it same in the case of using LM74670-Q1?

Best regards,

    Hi Teritama,

    ORing with schottky and LM74670-Q1 might not be feasible since LM74670-Q1 is ground less device and hence use the drop of body diode to charge the charge pump.

    With schottky, the drop will reduce, and startup will not happen.

    Regards.
