I want to drive 5 LED's of 1 watt each using AC supply of 230 v 50 HZ.
specification requirement:
(1) output 5 watt , 300 mamp of constant current
(2) Total harmonic distortion < 10%
While searching for the compatible IC in ti.com, i come across LM3444 evaluation module. Application note AN2082
I was going through this application note and found this warning message :
"Warning: The LM3444 evaluation board should not be powered with an open load. For proper operation, ensure that the desired number of LEDs are connected at the output before applying power to the evaluation board."
what if i power ON this evaluation board with an open load and why it is recommended NOT to switch ON with open load condition. Please help.
