Using an IRFZ44N, I made a simple LED driver and used an Arduino Uno directly ... is the TPS92512 which allows for control of high brightness LEDs using PWM which is internally controlled.

Sunpower’s DAP-04 DALI to PWM converter is designed to provide DALI control in LED lighting applications. The DAP-04 has a DALI input that can accept data from a remote IEC62386-101, 102 or 207 ...

Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s and an Arduino ... PWM channels on the chip in concert — one to control the current and one to PWM the LED.
