Diodes Incorporated | LED driver dimming
Posted by: alex.calori

Hello, guys!
Recently, I've been facing issue on dimming LED drivers from Diodes Incorporated. As example, the LED driver I'm in trouble with is: AL8843SP.
On datasheet, the manufactur says CTRL pin must be drive with: open drain output or push pull output stage. I build those circuits, but none of them seems reliably to drive that pin. In one way, or another, when I put all in test, the integrated circuit (AL8843SP) does not work properly and end up to fail.
If any one can help me, indicating a proper circuit (bulletproof) to dimming CTRL pin, I'll be very grateful.
Thank you very much!

That's a question that might be better directed to Diodes Incorporated.
