Am I seeing correctly? The middle of the 3 legs on the 7135 chip that’s ground doesn’t have ground under it, but there is a pad there… is this correct? That pin can be removed and with the middle of the board fairly clear a small post or pillar can be glued to the pcb. This can be the battery contact point, on the fet side of the board, with a connecting wire from the + via.
The MCU is too thick to be on the battery contact side of my TP.
Not gonna work. You’ve got to be able to get LED- back to the LED side of the board. Have you tried sanding down MCUs? I have not. I assume approximately 0.5mm can be gained in that way…
Anybody know how this fet ranks for this package size?
PSMN1R5-25YL,115
PSMN1R5-25YL datasheet
I went ahead and ordered some of these, from what I could tell they looked to be about the best choice…not like I’d know or anything though. I’d appreciate it if someone would take a look and confirm or throw water on em.
All I’ve done so far for this package is make this list over here: [WIP] *15mm* DD+single-7135 driver - single sided Dual-PWM compatible using 3.3x3.3mm FET
