thank you both, I think I'll go with your solution betwixt.
But I intended to source current, is it ok to sink up to 14 Amps? I read somewhere that it is better to cut Vcc than to cut GND?
And the transition time of the NMOS would be fast? Or it doesn't matter?
Is it feasible or recommended to dim the LEDs like this?
Or there is any easier, safer or cheaper way? I'd like to use 20+KHz PWM to avoid audible ripple.
Hello, I've ran simulations with this driver circuitry, tested it in my bench, and is working nicely, but I've never seen this configuration before.
If this topology have a name, what is it called?
And what cautions should I take?
I only need a max of 500Hz.
