MMPF0100NPEP main input supply voltage Vin

Can the MMPF0100NPEP main input supply voltage (Vin) be less than the switching regulators SW1AIN, SW1BIN, etc?

I would like to use the KITPFPGMEVME Programmer while my board is powered by the programmer (3.3V) or by my board's 4.2V DC/DC converter.

By placing two or-ing diodes from programmer 3.3V and external 4.2V the PMIC can be programmed with system power off or on.

Thank You,
