The source voltage regulator circuit for the chipset

On the mainboard there are 3 main voltage regulator circuits that are VRM voltage stabilizers for the CPU, RAM source and chipset power. The power supply for CPU and RAM is easy to determine because the CPU power can be measured through the output filter coil. And RAM is measured at the corresponding pins as 143 pins of DDR … And the power supply for the chipset is determined by experience mainly.

North chip: Use Vcore, Vcc RAM and add 1v5 and 1v8 sources LT1167CN8
South chip: Use directly 5V, 3v3 and 5V STB each of the main sources and also use 1v5 and 1v8 sources.
So when it comes to the source for the chipset, it is mainly about this 1v5 and 1v8 source.

How to define the circuit:
As mentioned above, defining source circuits for chipsets is mainly based on experience. Here are some experiences:
The voltage regulator circuit for the two chipsets is usually located in the area between the two chipsets.

When operating, the S pin usually has 1v5 to 1v8
Circuit usually uses 8 pin IC to control Mosfet.
Some newer motherboards use the same pulse source as the CPU VRM circuit so the circuit has coils

  • On different motherboards use many different types of voltage regulator circuit.
  • Different chipsets use different voltages.

Repair experience:

  • When checking the source level, just measure the S pin of the mosfet area near the chipset and between the 2 chipsets. If there is 1v5 or 1v8 is OK (For INTEL chip and VIA chip, SIS, NVidia … will be a little different)
  • Depending on the specific circuit type, it must be analyzed to find a suitable repair. The most important is what form it is. Determine which IC controls which mosfet and find equivalent ic to replace.
  • IC LM324 and LM1117 are very common so don’t worry about no replacement chip. Still used in the RAM source voltage regulator circuit.
  • IC RT9214 is a form with C – L filter, so it can measure the output voltage like the Vrm circuit of CPU. Equivalent can be replaced with the APW7120. This form is usually found in the RAM source voltage regulator circuit.

Integrated circuit design

Integrated circuit design, or IC design, LT1167CN8 is a subset of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs.

ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography.

IC design can be divided into the broad categories of digital and analog IC design. Digital IC design is to produce components such as microprocessors, FPGAs, memories (RAM, ROM, and flash) and digital ASICs.

Digital design focuses on logical correctness, maximizing circuit density, and placing circuits so that clock and timing signals are routed efficiently. Analog IC design also has specializations in power IC design and RF IC design.

Analog IC design is used in the design of op-amps, linear regulators, phase locked loops, oscillators and active filters. Analog design is more concerned with the physics of the semiconductor devices such as gain, matching, power dissipation, and resistance.

Fidelity of analog signal LT1167CN8 amplification and filtering is usually critical and as a result, analog ICs use larger area active devices than digital designs and are usually less dense in circuitry.
