I have a LED strip (16ft Hitlights Luma5 warm-white high-density) powered by a constant voltage supply. I'm considering adding PWM dimming with a Maxim MAX16820 constant current driver. The PWM signal is generated by a microcontroller monitoring a pot for brightness control. One difference from the reference circuit is that the LED strip contains parallel sets of three series LEDs with a current limiting resistor.
Some sources suggest that a hybrid architecture with a constant current driver and a constant voltage supply are beneficial (e.g. this reference).
In my case, is there anything that makes this a bad topology, or traps to consider? And what are the benefits of this setup?
