Hi Team,
Our customer would like to use the following conditions.
[Conditions]
-Vin=3.0V
-2cell Battery = 4.0V to 8.4V
-Iout= around 20mA
-Vout=around 17.5V to 21V (LED is 5 or 6.)
-Dimming frequency is several kHz
-Inductor is 2.2uH (This value is our customer demand. )
Therefore, we would like to ask you a question.
--------------
[Q1]
Our customer would like to separate “VIN” and " regulation voltage".
Because, they would like to use the 2cell Battery(4.0V to 8.4V).
Could you please let us know if you have any concern for this usage?
-------
[Q2]
If this usage is allowed, could you please let us know the startup sequence?
Should I apply "2cell Battery" first?
-------
[Q3]
I understand that the recommended value of inductor is 4.7uH to 10uH.
However, our customer would like to use 2.2uH.
Could you please let us know if you have any concern for this usage?

Regards,
Kanemaru
