Hello,

PMIC PF3000 Datasheet contains the following comments regarding voltage drop

for the SW2:

* The higher output voltages available depend on the voltage drop in the conduction path as given *

*by the following equation: (VSW2IN - VSW2) = ISW2* (DCR of Inductor +RONSW2P + PCB trace *

*resistance).*

The similar statement, which allows to estimate minimal input voltage, is also for the SW3;

but there is no such equation for the SW1. What are considerations for the SW1?

Sure,same with SW1.
