Yet another CN5816-based LED boost driver board design for 36v 40w COB LED, like CREE CXB2540/3040/3540.
Usage
- Provide a 20v, 2A DC input (e.g. from a USB PD charger)
- Hook up a 36v 40w LED, like CREE CXB2540/3040/3540 (I've tested with CREE CXB2540 for now), remember to put on a heatsink or otherwise it may become a bit smoky!
- It should work now
Fine adjustments
- According to CN5816's official datasheet and component calculator:
- When
Vin= 20v,Vled= 36v,Iout= 0.8A:-
- If Vled goes too high, try reducing R1 to 4260kohm
-
- If you don't want it to be that bright, or you can't afford a big heatsink, then try increasing
R6(theRsw) to something like 0.2ohm.
Caveats
According to Consonance FAE, when calculating the resistor divider for voltage threshold reference, the Vout here means Vin + Vled:
For example, my Vin is 20v, Vled (the LED's Vf) is 36v, then Vout needs to be 56v, not 36v.

Questions
How big is the GingerLight PCB?
It measures 28 × 52.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GingerLight use?
21 parts, built around the CN5816, MSK340A, CRSS052N08N and FXL1365-820-M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the GingerLight KiCad files?
From the huming2207/gingerlight repository on GitHub, at the commit this page was made from: the board is GingerLight.kicad_pcb and its schematic GingerLight.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GingerLight design in my own project?
Its repository states no licence, so its author keeps all rights: ask huming2207 before reusing the design.
