Hi,
I am bringing up a board and have not been able to get the TPS65261 powered up. One issue I notice is that the V7V pin never outputs any voltage above ~10 mV. From the datasheet, it seems like V7V should track the input voltage (minus dropout) to 6.3 V, but I never see anything at the V7V pin. Total current draw is 7 uA when VIN = 6 V with only the chip soldered to the board.
Here are some details of my implementation:
VIN = 7.5 V (although I have tried anywhere from 4.5 V to 12 V)
EN1, EN2, EN3, MODE all connected to V7V.
VDIV R1 = 36.5k, R2 = 11.3k
Any thoughts on why this could be?
Thanks,
Eric
