I'm using the TPS65631W in a design with AMOLED display. The 4.6V comes up and then immediately turns off in about 100us. I don't think it is the Short-Circuit During Start-up since it doesn't kick-in until 10ms. With no load (AMOLED), both voltages come up fine (4.6 and the programmed -2.4). The display consumes about 20mA during normal operation (NON-Startup). I have perform several tests with the displays and I believe they are operational.
I'm looking for any advice on how I should proceed.
