Other Parts Discussed in Thread: TIDA-00690,
Hi,
I'm working on a demo board similar to TIDA-00690. I have the same harvester and a TPS62122 has DCDC regulator.
With Vout=1.2V, Rload=120Ohms, 110µJ is available.
When I remove the DCDC and put a load at the output of the harvester, this one generates about 280µJ.
Then the efficiency of DCDC regulator is < 50%.
Is there a reason why the efficiency is lower as expected ?
Best regards
