    TPS51980B Vs TPS51980A !!!URGENT!!!

    can someone please tell me that can i use tps51980A or tps51980 insted of tps51980B??

    in schematics and in pdf ...they are both showing same signal and voltages..

    actually i am working on A2141, 16 inch macbook pro and i am suspecting TPS51980B faulty..but i dont have same part handy...but i have TPS51980A ...

    so can i use it?

      Re: TPS51980B Vs TPS51980A !!!URGENT!!!

      The TPS51980A and TPS51980B are both step-down power management chips manufactured by Texas Instruments, but there are some differences between the two chips.

      Operating Voltage: The TPS51980A has a minimum input voltage of 4.5V, while the TPS51980B has a minimum input voltage of 3.5V.

      Output Current: The TPS51980A is capable of delivering up to 1.5A output current, while the TPS51980B is capable of delivering up to 1.3A output current.

      Output Voltage Range: The TPS51980A has a fixed output voltage of 1.8V while the TPS51980B has an adjustable output voltage range of 0.9V to 5.5V.

      In summary, the TPS51980A is suitable for applications that require a fixed output voltage of 1.8V and can handle up to 1.5A output current, while the TPS51980B is suitable for applications that require an adjustable output voltage range and can handle up to 1.3A output current.

          so in short i cant use TPS51980A instead of TPS51980B in A2141!!

          thanks for your detail reply...

              Onkyo HT-R390 no sound output, video output ok
              by FrancescoV
              Good morning everyone,
              I'm trying to repair an onkyo ht-r390 that has no sound output, despite the volume being at maximum, the rest seems to work; the video output signal (coming from an hdmi input) is present, but the audio is absent. Similar situation if I send an audio signal from any input I have no output.

              The firmware reported is the following:
              M:1.00/11107BLP
              D:?.??/????????
              O:1.00/11107AL

              The DSP firmware given the question marks seems corrupt.

              On the BCHDM-0678 - 25140678 - QPWBCHDM0678A0 board the chip that usually seems...

              NTE Electronics “NTE5251K” Zener Diode 9.1V @ 50W Do-5.5% Want to build a 9.1 output from a 9.6 lipo4 battery pack
              by sam_sam_sam
              I have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
              I bought this from an eBay seller but unfortunately they only had one

              I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
              I bought three of from them to also make battery packs with this output power limit in mind

              I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery...

              Corsair CX750M [Model 75-002019] - burned output toroid inductor
              by momaka
              Looks like I may need a little help from the PSU experts (or anyone really! ) I have a Corsair CX750M (Model 75-002019) that I picked up for free about 4 years ago. This is the PSU:



              So here’s what’s strange about this one: it appears to work normally (normal output voltages) and any PC is stable with it. However, after a while (typically 10-20 minutes, but time can vary depending on the load), there is a sweetish smell of burned magnet wire insulation emanating from the PSU. Upon opening the PSU after this happened (many times), I was able to confirm...

              Troubleshooting PFC with SPC1012T not raising output
              by CoppellTVRepair
              It has been a long while since I posted here to ask anything....hope you can help.

              I have this Samsung power supply that uses SPC1012T as driver for the PFC and it's giving me a problem that I can't narrow down though I've troubleshooted and fixed hundreds of boards similar circuits.

              I am attaching a schematic from a different Samsung board, but the topography is very very similar if not 100% the same and it uses SPC1012T, which BTW is a pinout match to UCC28063 for which there's plenty of information. I haven't confirmed they are functional equivalents, but I strongly...

              Magnum IA.100 Amplifier Switches on, No Output, Possible Input Side fault?
              by flibidy
              I have here a Magnum IA.100 which belongs to my parents.



              The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.


              Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.
