Would you want to see a screen shot of the board and schematic or the Eagle files?
Les, thx for looking at this. I need help with the diode and inductor. Those are two things I have not researched, but will.You have missed out three parts that are vital to the operation of the AL8843Q. The inductor and the diode an Rset.

Is Rset the "set" pin 3?Les, thx for looking at this. I need help with the diode and inductor. Those are two things I have not researched, but will.
Thank you.
I forgot to put my .17ohm Rset resistor back in.....R set is the resistor that sets the output current on the AL8843Q. It is connected between pins 3 and 6, See the application circuit on page 2 of the data sheet. See page 12 of the data sheet for notes on the choice of diode. See page 13 of the data sheet for notes on the inductor selection. (Many of the graphs on the data sheet are with an inductor value of 47uH so that would probably be a suitable value.) It will probably look similar to the one on the LD24AJTA module. (The one on that module is 470 uH)
Les.
