Part Number:LM3433SQ-14AEV
Hello,
I recently purchased an LED Driver to make a projector brighter.
However, before I do any work, I want to test the main features of the LM3433. I am using a power supply to apply -12V, and connected a Luminous LED (SST-90) to the LED+ and LED- test post on the LM3433 to since its supposed to work with a current of 1 to 9A, and the LED driver is said to supply 4 to 20A.
My problem is that the LED is not ON. Am I missing something really basic?
