The Power Card delivers the possibility to change an input voltage from 5 V to lower voltages, according to the following table. The table shows the maximal output current and output voltages for the different revisions. Please consider the difference between the output voltages for the revisions.
| Iout Max | Vout REV 1 | Vout REV 2 | |
|---|---|---|---|
| EZ6301QI DCDC | 1.5 | 3.3V | 3.3V |
| EZ6301QI LDO1 | 0.3 | 2.5V | 2.5V |
| EZ6301QI LDO2 | 0.3 | 2.5V | 1.8V |
| EN6363QI | 6 | 1.0 | 1.2V |
| EN5339QI | 3 | 1.5V | 1.8V |
| EN6338QI | 3 | 1.2V | 3.3V |
| EP5358LUI | 0.6 | 3.3V | 3.3V |
