      Protecting against over volts when fitting a buck regulator controller. Good Idea?
      by dicky96
      Hi guys
      Here is a general question and I would like to hear your thoughts on it

      I've just replaced a very small 11 contact MP2329 QFN on a motherboard

      This supplies 1.8V STBY to the PCH - but the faulty one was only giving 0.7V

      Anyway I fitted it, but it is very close to the DIMM sockets and I can not clearly see down one side of it to make sure it has soldered properly ,even shining a torch down there. The other sides look OK under the microscope and also in a jewellers loop. This is the side that has two resistors that set the output voltage

      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 ?

      Issues in PWM circuit with LC filter to drive Peltier
      by vrasp
      Hi,

      I've been trying to build a Peltier circuit that I can control with arduino and create cooling ramps. I've never built a circuit before and only have a basic knowledge of electronics.

      I've been researching how to do this and attempted to build it. My circuit is basically a PWM signal sent to a motor driver with an LC filter to smoothen the signal. Since very low temperatures are required, I added another Peltier on top of the first one. The top Peltier needs to be driven at a lower voltage to limit the amount of heat produced and effectively lower the temperature....

      Need to buy buck regulator MP2329CGG but struggling to find supplier
      by dicky96
      Hi guys
      I need one of these MP2329CGG for a repair job. It's a 24V 6.5A buck converter. But I have not been able to find a supplier who has that component.

      Actually I would buy a few as I always think if I found one faulty already I will probably find more in the future

      I had one supplier on Aliexpress who gave me a price $2 each, but I have been waiting some days since I asked for shipping price and they don't reply

      Does anyone know where I can buy that part in small quantity (let's say 5 of them), or any equivalent I could use? it supplies the Standby...
