    Pick the right inductor construction for a desktop-CPU voltage regulator

    Pick the right inductor construction for a desktop-CPU voltage regulator
    Choosing the best inductor construction for desktop-CPU voltage regulators requires a good understanding of inductors and regulators.
    By John Gallagher, Pulse Inc. -- EDN, 4/27/2006
    Until recently, cost and the ability of a part to function in an application have driven the choice of inductors in desktop-computing systems' processor-voltage regulators. Designers have not been greatly concerned with component size, parameter tolerance, or performance requirements. As a result, inductor design for these systems lagged behind the state of the art. Over the past three years, however, the industry has begun to awaken, and vendors have proposed and evaluated several new inductor platforms to overcome new challenges resulting from changing regulator requirements.

      Very interesting read, keeping my venerable Epox 9NDA3+ in mind through that entire article brings up a thought or two about the design they employed... Too bad a redesigned voltage drop circuit would be necessary for the ferrite core power cube inductors...

          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...

          Lenovo S145 -15iwl vcore inductor warm.. looking with oscilloscope there is a spike.
          by Bartoloni
          Hi, i have a Lenovo S145 that after 20 seconds shutdown and restart (it's working correctly on thse 20 seconds)
          everything seems ok, but on Vcore inductor ( this is an i3 with just 1 switching power supply for CPU)

          there is an output to teh CPU with a spike.. seems that inductor can't handle the input...
          replaced the capacitor (330) and the inductor (R15) without any change
          any idea? very thank you!

          input of the inductor seems as usual... only strange thing is that the upper/lower voltages seems to be 21V (main power line is 19.3) ... but not sure this...

          How to read inductor specs?
          by badcap111
          I have a broken samsung galaxy s10 with missing inductor. I want to replace the missing inductor and I have found some vendors. But I don't understand how to read the specifications of the inductor. The specs are:

          INDUCTOR-SMD;470NH,20%,2520,T0.8,0.029OH

          I understand that the inductor is 470 nH with 20% margin, and the size is 2520 or 1008 (imperial measure), but what do T0.8,0.0290OH mean? I can't find any explanation on the web.

          Blown Inductor on WD My Passport
          by silver60618
          Hi Guys, my WD My Passport drive powers on, then powers off. Ive taken out the motherboard and identified a blown Inductor. Im trying to recover my data only

          Reading between leads show nothing. If I removed this Inductor, what would be a suitable replacement? am I correct that its a ferrite Inductor is to just filter noise?
          Ive seen people just bridge them, any harm in replacing it with a differnt value Inductor?

          Lastly am I correct in thinking there is no polarity on the smd component?

          Thanks!...

          uP0109: 2A Ultra Low Dropout Linear Regulator equivalent substitute
          by bilux
          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 ?
