Hello,
My problem is that the TPS65261-1 is not starting up.
In the datasheet is specified that Vin is possible between 4.5V and 18V.
I use 4.8V. In the datasheet is specified that the LDO of V7V provides 6.3V .. but how is that possible with lower input voltage?
Measurements:
Vin = 4.825V
VDIV = 4.777V
V7V = 0V .. is it possible that I need a higher voltage von 6,3V? But in the datasheed is specified that VIN has to be in range of 4.5V and 18V.
Here the schematic of it:
The both Resistors R308 and R309 are removed
The Resistor R310 it`s still there
