From the project
Dali Driver for 48V DC Input Voltage with CCT Control
A production-oriented KiCad 8+ reference design for a 48 V SELV, 30 W maximum, DALI-2 DT8 Tunable White LED driver with the following key features:
This design uses a common regulated 4-switch synchronous buck-boost LED bus (nominally 44 V) followed by two independently controlled, linear low-side constant-current sinks (WW and CW). This is the correct representation: a single regulated voltage bus with common LED anode, and individual current control on the low side per channel.
