Hi Everybody.
I'm wanting to use a Diodes Incorporated AP3032 LED driver in a design. (
http://www.diodes.com/_files/datasheets/AP3032.pdf) The datasheet says that, by default, you can just hook the OV pin to the output to set the max voltage to 27V. The example schematic though shows a voltage divider there though, and the resistors are unlabeled. This implies a variable setting to me, but there is no more detail given.
A similar (but much more expensive) part is a Linear Technology LT1618. (
http://cds.linear.com/docs/en/datasheet/1618fas.pdf) They have a pin serving the exact same function, and they were nice enough to specify the relation between divider ratio and cutoff voltage.
Does anyone see how I can set a specific cutoff voltage on the AP3032? 27V feels way too high for my application. I'd rather set ~5V.
Thanks,
Craig
