    Help Identifying an IC chip

    hello folks
    I need some help to see if anyone can Identify this (IC) I believe its a Reg of some type I will post some pics as well. its in a test equipment hand held network tester its part of the power side of it its a 6vdc rail only thing on the chip is as follows (BPV 7CK EYL9) Its a 10 pin Plus bottom ground plane
    I am including a layout/pinout of the ic and what i had on the traces that go to the Reg as best as i can see and test pins 2 and 4 were shorted is what i found with the ic under thermo cam it was getting 300+ almost instant pulled off pcb and no more short now need ic chip to replace but cant find the part numbers i have tried turned up nothing thanks for any input or info

    I did find this but not sure how reliable it is thanks
    TPS63002DRCR TPS63002DRCRG4 TPS63002DRCT TPS63002 BPV【IC REG BUCK BOOST SYNC 5V 10SON
    after checking the schematic for these it sure looks like it the only thing is there power rating for the ic is 5.5v and for a 1 0r 3 cell battery and i have a 4 cell battery 1,5 x4 =6vdc am i missing something?

      Does the Vin connect directly to the + of the battery or is there a component in between. This is likely the correct part.

          The TPS63002 you stated in your post is almost certainly the right IC: checking from Texas Instruments' datasheet for the chip @ https://cdn.badcaps-static.com/pdfs/...58e6a1d45f.pdf, it says that the maximum recommended voltage is 5.5V, but that the absolute maximum rating is 7V (see Section 4). It's probably a case of the device being built on absolute maximum ratings without much thought put in, i.e. "it's less than 7V so it must be okay"

              thanks R_J and RegorForot for your help I have ordered the IC chip from mouser I do think as well this is the right IC and yes there is a protection diode before this IC so that makes sense there would be a voltage drop from the diode I just got in a hurry but after thinking about it and looking at the layout it made the light come on lol thanks for your quick response I will post back again once I get the part in and installed.

                  Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
                  by acedogblast
                  This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

                  There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

                  ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
                  by DynaxSC
                  Hi

                  I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
                  The SPI chip is an Winbond 25Q256JWEQ model (1V8).
                  The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
                  The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

                  I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...

                  Requesting help identifying chip in Macbook Pro A2485
                  by Loki_Fido
                  Hi ya folks,

                  I have this MacBook Pro A2485 (M1 Pro 2021) which came in for repair.

                  It had a shorted SSD power supply chip. Therefore it was stuck at 5V.
                  I replaced it and the SSD are fine. No more shorts.

                  But The mac still pulls 5V and 200mA. If i leave it alone for 5 mins, the mac manages to receive 20V and 40mA. Of course, which doesnt mean the mac starts after power meter reading 20V.

                  But while the mac is stuck at 5V, i checked the board with thermal and found this chip was trying to start. Chip picture is attached.
                  Chip marking...

                  Common SPI bios chip programming Questions and Answers
                  ----------------------------------------------------------

                  Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

                  A: If you can`t read from it how do you expect to write to it ?.

                  Q: Why is my bios chip unreadable ?.

                  A: The programmer is faulty or has a worn or broken zif socket.

                  The USB cable is frayed,connector pins worn or some other physical damage.

                  Not enough amperage or voltage to power the programmer properly.

                  Help identifying this chip for Yoga 7 16IRL8
                  by trepachka
                  This chip is shorted thru. Based on what I see, it's either a 3.3V or 5V buck converter, just my guess. The markings on the chip state "S2=AB".

                  A photo of the chip is attached.

                  Thank you....
