What would be the best, or a least a good chip for a current regulated driver?
Are the AMC chips used on the Chinese drivers used because they are a good efficiency/price or because they are cheap?
Looking at the
Looking at some of the maxim offering I find chips that fit the bill for current out and voltage in but don't have a dimming option.
How are the AMC chips dimmed? Just by turning the whole chip on and off via PWM?
I am trying to find a small enough chip that I can shove some sensors onto a custom driver (3-AX Gyro, current meeter, compass) with a decent micro-controller and still have it fit into a p6 style dropin/host.
Thanks to all in advance.

LM3410 from National, it would give 2.8A from a single tiny chip and allow for PWM dimming on pin 4.
