03:23:46 <arch> oooh pretty cool: https://www.ti.com/tool/PMP9581_REVB and https://www.ti.com/tool/PMP9581_REVC
03:24:12 <arch> i do have me some salvaged synch buck controller ICs, so i could make a smaller variant, with the SRF1280 coupled inductors
03:27:27 <arch> fuckin renco...those bastards never replied to my query
03:29:09 <arch> also TI's test methods when using thermal camera are often flawed. they didn't put electrical tape or whiteout on the shiny metal parts. infrared emissivity are gonna throw off readings

09:04:48 <arch> what are the downfalls of this design? https://www.ti.com/lit/an/snva795/snva795.pdf it's a high side nmos, non synchronous buck regulator, used in non-inverting-buck-boost configuration.
09:05:59 <arch> the ripple appears to be crappy, though transient response seems okay
11:24:18 <rust_collector> yeah, crappy ripple response. I would look for a thing

12:38:02 <arch> the fucks capacitor?
12:39:26 <rust_collector> do it! you need a new dialator
12:43:48 <arch> it has a habit of prematurely discharging, that fucks capacitor
12:44:35 <arch> electrolytic dysfunction
12:45:16 <DogWomble> just make sure it's not so worn out that the magic smoke gets released
12:45:49 <arch> friction burn...gotta use some good old dielectric grease
12:49:46 <rust_collector> oooh
12:51:23 <arch> please keep moans of ecstasy to yourself
12:57:10 <DogWomble> what about signs of disappointment/
12:58:06 <rust_collector> disappointing ecstasy is a weird feeling.
13:17:38 <arch> !twss
13:17:39 <EEVBot> That's what she said!
14:00:58 <rust_collector> that's why satan snores?
14:08:42 * arch sticks a plunger onto electrohead's scalp and goes to sleep
14:44:06 * rust_collector rips the plunger off, and takes multiple pics.
14:44:47 * rust_collector plops the plunger back on electroheads scalp
