Hello,
I'm currently working on a battery-powered project, in which I'm using a PWM signal to control an LED. For the first prototype I used the PWM signal to control a MOSFET, but also calculated and ordered parts to make a circuit based around the TI LM3405 Constant Current Buck Regulator.
My question is whether it's worthwhile to use the LM3405 driver for the LED in this system, where the LED is the only load. Since I'm already driving both with a PWM signal, I should be getting a much better efficiency, so am I going overkill using this dedicated driver IC?
Thanks!
