Could I use LM3464 not using DHC?

If it is ok, should I open VDHC, CDHC, OutP and VLedFB?

Hello,

It should work without the DHC. You may still need to have VLedFB connected for start-up reasons. I will find out more about this.

Hello Yokota,

I found out more regarding this:

"VLedFB is needed for setting up the correct operation of LM3464.
If DHC is not needed, OutP can be left open. However, CDHC and VDHC are still suggested to have decoupling capacitor being placed."
