Hi:
I'm working on the TPS65100 right now. It works fine when the input voltage is around 3.3V. However, if the input voltage is 5V, the chip takes a lot of current even without LCD connected. Usually, when the chip is driven with 3.3V without load, the current is around 60mA, but if the input voltage is 5V, it takes around 700mA. I checked the output voltages are all correct, and there seems no shorts. Not sure where those current goes. The schematic is below.
Thanks in advance.
