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.

but instead he included is own controller. An Arduino drives the switch-mode power supply, offering dimming thanks to PWM, and the ability to automatically switch the light on and off using an RTC ...

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 ...
