Good day. Does anybody have datasheet for this one? Its a pwm controller with code UP6128PD. I need to check if I have substitute for this one. I attached image for reference only. Hope someone has Thanks!

Re: Need Datasheet for this one
had a look boardview K55vd (pu8901-pu8301)and compare it with asus n73sv (page82-83), seem up6128pd compatible with rt8202a/b. but not sure 100%. if you want to try it. its your own risk

Re: Need Datasheet for this one
Thanks meritosari. Actually its the exact motherboard I'm fixing, Asus K55vd. When I press power button, all lights turn on but processor fan does not spin. There's no display and cpu does not heatup. I checked motherboard and found short on PL8905 which led me to this IC UP6128PD (pu8901). A closer look revealed corroded pins on 1,2,3,14,15 and 16. If I can confirm RT8202AB is compatible, it will be much easier to find. thanks again

First post -Intel NUC 10i5 -BXNUC10i5FNH not powering on -IC burnt- request for IC details/datasheetHi all,
I came across this very active forum with knowledgeable folks on electronic circuits and components, while google searching for the details of my burnt IC marked 7603 in Intel NUC board. I joined this forum today and this is my first post here.
I recently got an Intel NUC 10i5 and had installed Linux Mint and was using it for about a month when it died suddenly and did not power up after that.(Power Adaptor is ok). When I opened the NUC , there was a burnt IC marked 7603 (and ILCB in second line). I am unable to find the details/datasheet of this IC. I will be grateful if... -
Hi, pulled this component, (I'm assuming it's a MosFET) from an LED COB video light. Im trying to find the datasheet so I can find an equivalent replacement but no luck. Any assistance with the datasheet would be appreciated.
Failing that, a way to pick a suitable replacement component? If it's indeed a switching fet, I'm assuming I might need to measure the switching clock frequency and find a component that meets the power capacity?
Its a pair of them driving a 130w Light. Takes in 19volts. I can borrow a scope to measure the switching freq.... -
I got a dead HD6950 on Ebay to try my luck and repair it. There were a few broken off capacitors that I already replaced.
Measuring the PCI-E lanes I got somewhat weird measurements, the gpu might or might not be dead.
If I plug the GPU in, the core heats up and I also get VCore but on two inductors that measure 16 and 60 Ohms respectively (Memory and PEX I guess) there is no voltage.
On one of the two buck-controllers (APW7165) the enable pin is pulled to GND and the other controller I just cannot find a datasheet for.
So if anyone has a datasheet or at least... -

Hello again Community
Anyone verse on how you go about choosing a substitute mainboard for your TV repair. Like the chap in the video below sometimes a 1:1 replacement board is too expensive and reballing a mainchip(s) maybe outside of your skillset
. In the video the poster states one needs to match the replacement board with the SMPS, T-con (if not built in) and panel (and substitute cabling be also be required).
I'm very interested in choosing a suitable replacement board for any model or make of TV and the general (or detailed if your willing) step this entails....03-23-2024, 02:55 AM
