Hello,
I'm currently evaluating STEVAL-ISV020V1 using AN4397 and I'm not reading any voltages from both LDO outputs.
Here's my setup:
- PV_in: 2.6-2.7 V PV
- BATT: 5v supercap
- SW1 and SW2 enabled
I can confirm that the supercap is charging as STORE shows ~3.9-4V and BATT shows a gradually increasing voltage which reached >3.3V per my last test. SW1 and SW2 are enabled as both LDO_EN pins in CN3 show ~3.9-4V. UVP shows ~1.2-1.3V while EOC ~1V.
However, I am not reading any values at all in LDO1 and LDO2 in CN2. Am I missing something in my setup?
