TPS2561: Different supply voltage to TPS2561

Part Number: TPS2561

Hi,

I'd like to seek for your advice if we could supply two different voltages to TPS2561/TPS2561-Q1/TPS2561A as per diagram below?

Thanks

    Hi Eng,
    Since the device input voltage is from 2.5-6.5V ,so 1.2 V will let the device go to undervoltage protection .
    The deive internal Vin is conect togeter., so we can't use two difference voltage for input at the same time .
