Hello
we designed 3.3V and 1.2V for a Delfino uC input voltages.
channel 1 is the 3.3V - we get 1.25V
channel 2 is the 1.2V - we get 1.2V
the diode D8 is to match as much as possible the rise of the voltages for the uC.
another point to mention - when power is off, we see a short circuit between the outputs (using buzzer function on a Fluke) - even if we remove the diode D8.
The output voltages are pretty smooth without any spikes.
the question is how can we debug this device?
here is the schematic:
In another thread on e2e I saw that it might be an issue of the device itself...here's the device. can you please confirm the marking is ok and this is an original part of TI?
Thanks a lot!
