Other Parts Discussed in Thread: TPS22910A
Hi All,
I am using TPS61220DCK in my design for a while with 3V input battery to generate 3V stable output even if input voltage goes down till 2.0V. It works perfectly alright.
Now I would like to use 1.4V Zinc-Air battery as input to the device and would like to generate 3V at output.
When I supply 1.4V input to TPS61220DCK it only shows 1.5V at output. I tried connected 2 Zinc-air in series i.e 2.8V at input, still the output is 1.5V.
I am attaching my circuit for your reference. Can someone help what could be going wrong.
Regards
Lakshmikanth
