Copy-pasting Laxman's explanation

Palma have SMPS10 regulator which can generate two voltage level 3.75 
and 5V.
This SMPS10 has the two outputs OUT1 and OUT2 and having one input IN1.

SMPS10-OUT2 is always connected to SMPS10-IN1 via following logic:
- Through parasitic diode (no sw control)
- In bypass mode (bit  configuration is there to enable/disable Bypass)
- In Boost mode (bit configuration is there to enable/disable Boost mode)

SMPS10-OUT1 is connected to the SMPS10-OUT2 pin through Switch (SW 
control for enabling/disabling this switch).
