Hi team,

I have two questions which are showing as below.

What is (1.2V)VBG difference?

We found that the Vboost_max is different between LP8867C-Q1 and TPS61194-Q1

One is LED max voltage*amounts + 3~5V and the other one is LED max voltage*1.3*amounts, could you let me know the reason?

Hi Roy,

1. Do you mean the range of VBG?

2. The requirements are to meet the headroom voltage of current sink and different description means different margin for voltage margin.

Hi Roy,

The range of VBG has been provided through mobile phone. Please help close this thread if you don't have any more questions.
