That tiny thing with the letters 11G on top is using some 2×2mm package, being right next to the bulk of the driver's (copper) cathode. I think it must be some MOSFET.
You mean that, when the driver detects high input voltage, that tiny and poorly heatsinked A00D part is the MOSFET? Well, I don't think so. I could know more, but that looks to be part of the current control feedback stage, or sort of. :???:
So if that AOOD is not control mosfet it will be need only for turbo. From PCB traces I can see that. If another device is main switching mosfet how the circuit will work from low voltage AA battery. Also input LDO, OPamp will need higher power supply voltage. Another way is if MCU stared to work from 1V and if it control PWM signal for mosfet based boost converter. But I’m not very sure is that in the case.
Hello! I'm here to ask a little question (for Simon). I just received an M2 host ordered nearly two months ago (thank God its home now, there's been many delays with airborne mail shipments). I ordered it because I thought it used the same size reflector as the M1 (after all M1 & M2 reflectors are for sale in this Convoy store advertisement), to build a pocket thrower.
However, having the M2 side by side with my M1 makes me dubious. The M2 head is appreciably slender, and looking at the front of each to my eye I'd say the M1 reflector is a bit bigger. Still no measurements taken, I must admit, my M2's head is still unopened. So I am somewhat confused, is the M1 reflector actually bigger than the M2 reflector? Because if so… :facepalm: Never mind. Yes, the M2's reflector is slightly smaller than the M1.
Still, the M2 looks great and more pocketable (M2 reflector size ∅28.9 × 22.8mm). I wonder what are the actual differences in throw versus an M1 (M1 reflector size ∅31.8 × 23.2mm). ≈81.17% is M2's reflector area versus M1.
Hi, I have question about Ali Convoy store. I want to buy some items but when added them to basket I was charged with shipping cost for every single item. It’s that normal. I can’t understand why shipping cost is the same for one big item or single little driver. It is possible to get get some combined shipping from there?
Aliexpress’s delivery setting is not user-friendly,
you can place an order first ,but dont finish the payment ,then leave me a message to let me adjust the amount
Hi, I’m owner of several Convoys, the last a S2+ sst40, a very good flashlight, but today walking around closed mountain I had to move the flashlight up and down because it is a bit thrower. I’d like something more flooder in 18650 to complete my S2+ sst40, sst20 and xml. xhp50.2 3v is a bit efficient than the other from 1A, so, could you consider make a S2+ xhp50.2 3v with the same driver as sst40 has? For outdoor walking the weakness of xhp50.2 3v are irrelevant, but it’s floody beam and better efficiency a what I am looking for, and perhaps some people. Something between sst40 spot and a mule is perfect for walking outdoors and seeing at the same time the floor and tree branches at head height at the same time. Better efficiency can also help to keep some more lumens out.
Thanks in advance, Arturo.
