Does anybody know if I can exchange this regulator for a different on as I have got this part tps51212dscr ?.
Many thanks

Re: tps51212dscr equivalent
What's that...
Buck controller or other regulator?
What's the mobo number?
Do you have mobo schematics?
I couldn't find any datasheet...Last edited by loser18; 05-16-2014, 06:29 PM. -

Hello everyone,
I want to find a replacement for uP0109 8pins, and i found this parts:
uP0109 is "2A Ultra Low Dropout Linear Regulator"
RT9199 is "Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator"
FP6137C is "2A BUS TERMINATION REGULATOR"
can replace uP0109 by RT9199 or FP6137C ? -
Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...

hello,
i have a hp display 2311 to repair, totaly dead
on the board, il have 2 capacitor 470µf that are dead and the 3.3v regulator : ax6630-33
i have no such regulator, can i replace this one with a mic5209-33 (3.3v outpout regulator too) ?
thank you -
so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!!
what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol! 
i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing... -
Hi everyone,
I’m trying to identify a step-down regulator marked AMCH073. It’s used on the PEX power rail of a graphics card. I can’t find any datasheet or info online.
Here’s what I’ve observed:
• It has a QFN-16 footprint, similar to NB670.
• Pins 1, 2, 15, 16 are connected together and go to the inductor, so likely SW (switch node).
• Pin 9 is connected to GND, which doesn’t match NB670 (where pin 9 is SW).
• Pin 8 also seems to be tied to the same GND plane.
• The chip only says AMCH073, no manufacturer logo or other markings....
