Re: IC Marking Codes and Datasheets #2

Never had to ask before, but this IC a SOT-23-5 is marked with

K2N18

Pin 1 has ~600mA
Pin 2 is GND
Pin 3 seems NC
Pin 4 is 1.8v directly next to a 100K resistor to gnd
Pin 5 is 3.3

It's on the EDP circuit, possibly BKLT or EDP PWR? One cap blew and pins 1-2 are shorted on the bad device

One website says it's a RP400N301B (smdmark)
The board is labeled with NB3029_MB_U_V4 and the FRU is 5B21C22573
The machine is a Lenovo Ideapad 5 Pro 16ACH6

It could be an Excelliance MOS EM5203AJ-20 .An NB3029 schematic and boardview is available on some paid sites,if you request them in the schematic requests section someone might post them.

Good grief that was fast. Yeah I think you nailed it! I've requested the schematics with another resource, I will post here if I get no love.

Badcaps is the best. SMDFlea is #1

Re: IC Marking Codes and Datasheets #2

I've found a SOT23-6 with marking |AZEM that looks like MPS made, but it's not in your list. Any idea?

It's in the secondary side of a Chicony USB-C laptop charger (A18-045N1A).

It could be MP6908 / MP6908GJ-Z .Here`s a datasheet https://cdn.badcaps-static.com/pdfs/...ec0f4ff6e6.pdf

Hello

Could you help me with this one?

X25C
6020B

I think it should be a RAM IC.

Re: IC Marking Codes and Datasheets #2

Hi, I'm hoping this is in the correct thread. I was hoping that someone would be able to assist me with locating this component its from an oculus controller and this is pumping out a lot of heat. I have checked for shorts on capacitors around it but none located thanks

Re: IC Marking Codes and Datasheets #2

MPS # MP1471AGJ-Z

Wrong, because picture shows a SOT23-8, and this one is a SOT23-6. Also, top marking in picture is ACM and this one is AGM.
Then, it's a MPS MP3414DJ.

Thanks! My bad fading eyes.

Re: IC Marking Codes and Datasheets #2

It is MP2015AGG QFN-6 (2mmx2mm)

Re: IC Marking Codes and Datasheets #2

Now I'm trying to identify a buck DC-DC IC, SOIC-8 package (I think no exposed pad), pin 2 is input, pin 3 is output SW, pin 4 is GND, and marking is GMDAE in large letters, nothing else. Possibly chinese. If that helps, there's another buck IC in the same board with same package, pinout and letter style, and marking is GoEAX, possibly same manufacturer.

Post the motherboard model number please

Re: IC Marking Codes and Datasheets #2

It’s not a standard motherboard, it’s an arcade machine emulator from SNK MVSX.
