This is still not making any sense. The quality of regulation and
output voltage are essentially orthogonal, and obviously there's a
specific API for bypass which is something different again to both
mode and output voltage selection.
Do you recommend adding API's (similar to bypass) for BOOST and SWITCH?
No. A boost regulator is still a voltage regulator, it just happens to
raise rather than lower the voltage but it's otherwise a normal
regulator. I'm not sure what you mean by "SWITCH" - from the name it'd
just be a bypass?
Copy-pasting Laxman's explanation
Palma have SMPS10 regulator which can generate two voltage level 3.75
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).
