I want to drive 3x 1W LEDs in series rated at 350mA. I want to control their brightness. So my question is could it be done by feeding PWM signal to the EN pin of LMR62421?
I will be powering up the circuit using a 4V supply and boosting it to 10V with 350mA current output to drive LEDs.
I have not done much power supply design, so go easy on me.
