    MPS2329C and MPS2329 voltage regulators -are these compatible?

    Hi guys
    I need to replace a faulty MPS 2329C but I have some MPS2329 regulators

    These look like they could be compatible - the difference is that the MPS2329C says 'Synchronous Buck Converter with Forced Continuous Conduction Mode (CCM)' and the MPS2329 says 'Synchronous Buck Converter'

    The pinouts are the same, and the product descriptions are the same. So what is this Forced Continuous Conduction Mode, is it just something to improve efficiency? So does it matter in my case (mine is used to generate 1.8V from 3.3V standby on a desktop motherboard)

    Can I replace this

      Yes it should be ok. "Forced Continuous Conduction Mode, is it just something to improve efficiency?" yes .

          Thanks for sharing this information
          Have you used this type

          Synchronous Buck Converter with Forced Continuous Conduction Mode (CCM)' and the MPS2329 says 'Synchronous Buck Converter'

          Not this exact part but something similar

              ThinkPad W530 - faulty CPU regulators?
              by yuii
              Hello
              I've got two W530 boards, one with K1000M and one with K2000M graphics card. The first one had an issue of turning off under heavy CPU load after about 30 minutes or in idle. GPU load wasn't causing it to shut down. Trying to turn it back on would only make the power LED to come up for about 2 seconds without fan spin or thinklight flash, and that's it. It also wasn't charging the battery after it died.
              Gently pressing the laptop in left upper corner would fix this problem for a couple of days.
              The latter is completely dead and has the same 2-second power blink, nevermind...

              Dell 2007FPb with 4 buck step-down regulators
              by seweryn
              I have monitor Dell 2007FPb. It was working good. Some day it was shut off and stay dead.
              I checked some voltages on the boards. I read this thread:
              https://www.badcaps.net/forum/showthread.php?p=335335
              and very usefull budm posts ( thanks buddy, it was great work ... ).
              My damage was typical: 3A fuse burned and ZD701 diode was shorten.
              So my board is in few points different than other described in citing thread. On my board are 4 buck converter regulators. Apart regulators 3.3V (Q6), 5V (Q14), 12V (Q9), is ther fourth, build on MOSFET Q2. Two TL1451 has together...

              RT8015B RT8015BGQW RT8015BGSP Datasheet
              by Document Archive
              The RT8015B RT8015BGQW RT8015BGSP are high efficiency synchronous, step down DC/DC converter. Its input voltage range is from 2.6V to 5.5V and provides an adjustable regulated output voltage from 0.8V to 5V while delivering up to 3A of output current.

              The internal synchronous low on resistance power switches increase efficiency and eliminate the need for an external Schottky diode. The switching frequency is set by an external resistor. The 100% duty cycle provides low dropout operation extending battery life in portable systems. Current mode operation with external compensation allows...

              Dell Latitude 5420, Coloured screens from one colour to another continuous.
              by Dan20701
              Hello all, I have a Dell Latitude 5420, before I upload the bios I thought I would ask. All I am getting is are coloured screens from one colure to another continuous that's all its doing.
              I have searched on google some say this is a graphics problem and not a bios problem. I did try another bios file from the forum it stops at the Dell logo.
              With the original chip fitted I am getting error code 3 amber and 3 white flashes.

              Any advice please ?.​

              KingWin ABT-650MM 650 Watt ATX PSU [PCB: SW8835REV:A]
              by momaka
              For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
              http://www.rmac.kingwin.com/products.../abt_650MM.asp

              I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.




              What mostly drew me into buying it is its 2x PCI-E power connectors...
