nPM1100 modes

[monoo]

Hello all,

planning to use this PMIC and have one doubt about modes and features supported. 

Base on datasheet it is possible to fix the input current to 100 or 500 mA. I am not sure if it is possible to use the Buck converter under one of these configurations.

configuration table for fixing current:

sample configuration table

Configuration examples in datasheet, show not used.. means not possible to use ?

thanks for hints

Hi, 

no, "not used" does not mean "not available", it just means that is has not been configured in that specific reference circuit. 

BUCK is enabled by making the proper connections for DEC, SW and VOUTBSET0/VOUTBSET1 (see section 6.3 in the product spec)
Example, these values will give 1.8 V on VOUTB regardless of VBUS settings.  

best regards 

Robin
