>If not, you will need to add a regulator. I have found these step-down regulators that I would fed with 12V to output 8V regulatedhttp://www.dx.com/p/dc-dc-27v-to-24v-12v-3v-buck-car-power-constant-current-regulator-circuit-board-285001#.VAqrf2Pisxkor this:http://www.dx.com/p/mini-dc-dc-adjustable-voltage-regulator-module-blue-151211#.VAqrlWPisxkDo you have an advice?Thks
I'm hacking a PC PSU to get a regulated 12V in order to do the tests you suggested
I haven't found the Output Enable (OE) for PWM.
When output enable (G) is held high, all data in the output buffers is held low and all drain outputs are off.
but SCK (Serial Clock) is Shift Register Clock or Register Clock?...
I understand that dimming with a resistor (versus PWM) is not efficient (higher power consumption?)
