a NTC could be added to one of the programming pads for sure if vias gets added or drilled
adding a ground pad for it as well should be no problem next to the inductor
So let’s say we build a XHP35 triple in a S2+ shorty using these drivers. 6A at 12V gives us… 3x 2A per XHP35 so that would be 3x 2200 lumens for around 6600 lumens. Not too shabby
What I’m really looking forward to is efficiency on the medium modes combined with a good UI. A quad 9050 219C can do around 800 led lumen at 6W, if the driver is efficient enough I think something like 600 lumen OTF for 2 hours should be easily doable with a single 18650. That combined with bistro and the option of doing 30W bursts on any battery level, all in a very compact light, would be amazing.
Do we have any estimate for how efficient it will be at around 10W ?
Only interested in this design too. Loneoceans did release his stuff, but to my knowledge no one other than him actually built one. Now he ain’t here no more.
basically why I was not happy with poor cooling of the boost chip with no viases to the other layers and the option to put more boards on a Seeed 10x10 board in production
and I got no Eagle, no advanced license for it and I think getting used to a 2. program is too much
