I am currently trying to re-configure the ADP5092. This is the behavior that I am looking for :
-Vsys = 2.4V constant to power up my microprocessor
-Reg_out = 3.6V constant to power up another ADP
According to the datasheet, if I want to fix Reg_out = 3.6V I have to set Rvid to 27.7kOhm (currently 55.6kOhm on my schematic as I was delivering 3.3V before).
For fixing Vsys, according to the datasheet there is this formula :
- Vref is supposed to be fixed around 1V according to the datasheet, but when I look at the voltage on the oscilloscope I can only see this signal, do you have an explanation for this ?
- The thing that I don't get is that Vbat = Vsys, do you have an idea how to change this ?
Here is the current schematic that I am using :
Thanks for your help,
