ElmorLabs EVC2SX Voltmod Step-By-Step: Inno3D GeForce GTX 1650 GDDR6 Twin X2 OC | SB#42

The ElmorLabs EVC2 enables digital or analog voltage control using I2C/SMBus/PMBus. The device also has UART and SPI functionality. It can be considered the foundation for the ElmorLabs ecosystem as you can expand the functionality of some ElmorLabs products by connecting it to an EVC2.

In this case, we're interested in the 3 VMOD headers that provide digital voltage sense and feedback adjustment capabilities for analog VRM controllers. It works using an onboard current-DAC that sources or sinks current into the feedback pin. For a detailed overview, you can refer to the tutorial on ElmorLabs' forum: https://elmorlabs.com/forum/topic/evc2-vmod1-header-tutorial/. Please note that different versions of the EVC2 are using slightly different configurations for the onboard current-DAC.

I'll try to keep the step-by-step explanation as practical as possible in this video.
