Hi Team,
Our customer would like to know about external component of VDDH charge pump.
--------------
[Q1]
We understand that the function of 100nF between VDDH_D and GND is bypass capacitor.
Is my understanding incorrect?
If this capacitor is not connected, is there a possibility that VDDH charge pump(VDDH_D) can't output?

[Q2]
Our customer would like to change the output of VDDH(22V -> 20V).
Therefore, they are changing the resistor between VDDH_FB and GND(47kohm -> 52.4kohm).
We guess that it don’t have any problem there.
Is my understanding incorrect?
Could you please let us know if you have any concern?
