Hello,

In HV9911 boost controller, the source current sense reference voltage and the output current sense voltage are set bu potential dividers from the REF pin.

But can we use the same divider to input into both IREF and CLIM pins?

...the datasheet unfortunatley does not say what is the bias current drawn by the CLIM and IREF pins, so i cannot tell.

Do you know if i can use the same potential divider to feed both CLIM and IREF pins?
