Redid the buck-boost loops, the old ones were quite cruddy…. (new vs old)
Rearranged some capacitors, added the high power input, drew the schematics for rj45 transcievers, routed rj45 transcievers, and more stuffs
Yay! super awesome sauceum marathon where I implemented a new buck-boost converter, fixed (and triple checked) some symbols, and laid it out. This time around, I went with the LM5118MH and two external BSC014N06NSATMA1 N-channel MOSFETs, these ones are much better at getting rid of heat than DPAK FETs are. But my love for DPAKs continues; the schottky diode on the output comes in a DPAK package! just a little issue, though, kicad really does not like DPAKs…. I have had to adjust nearly every single symbol using one. Maybe I´m doing it wrong…? anywho, I am using 80TLV180M12.5X13.5 for the capacitors and PM5405.472NLT for the inductor. ((the diode is V10100S-E3/4W, and I have also yet to add one »)) hopefully the finishing touches of this bit won´t be too tedious. I´ll have to look over this power routing some other time, too
Rewired the FETs for the dual ideal diode OR-ing power MUX
Robot arm, robot arm, epic robot arm. I spent an entire hour making a schematic for the LM5176PWP for one of my power stages, only to later realize that the current loops mayyyy be a little troublesome, especially given my FETs of choice- the IRF3806TRPBF in a DPAK package…. I suspect that the LM5176PWP was designed with another FET footprint in mind but, I, being the cheapo (no, just kidding, I like DPAK and I would prefer to keep using these specific FETs as they are…. Okay, I just made a realization halfway through writing this- guess what. Kicad, for some reason, makes pin 2 of a DPAK the gate. where… it is usually the drain. So, this entire time, even before posting this project here, I have been wiring everything in entirely the wrong fashion. yay. Well, that´ll be fun to correct!
