We are experiencing unexpected behavior using the PMIC. See the three cases below:
| Test | Vin | Vout | i | comment |
|---|---|---|---|---|
| 1 | 3v | 3v | 7.9uA | expected supply current similar to system current |
| 2 | 2.5v | 3v | 12.6uA | expected supply current increases as supply voltage decreases |
| 3 | 3v | 2.5v | 17.5uA | UNEXPECTED PMIC in pass through mode draws more than 2x system current |
All tests done in auto mode.
In test 3, current is the same in auto/passthru/lowpower/etc
You can also see the current waveforms on the connected PPK for these three tests below.
Thanks
