Hello 🙂

It can be used with the VMOD header for voltage control and monitoring. There's unfortunately no I2C interface on uP9511 for further controls or monitoring. There's further information here on how to connect it: https://www.elmorlabs.com/index.php/forum/topic/evc2-vmod1-header-tutorial/

Hi Elmor,

is there any plan to support the IR3563B?

I want to do an epower from a dead 280X and EVC2 support would be handy.

Thank you in advance 🙂

Now there is 🙂 I suggest you jump into Discord so I can send you a test version and get feedback in real time.

You can try with this version, should be similar to the other IR356x controllers: https://1drv.ms/u/s!Atmpv-6qHr_6y4BUc1CBUDKWpD-C4A?e=hMzibe

Thank you very much. I'm going to order EVC2 and as soon as it arrives, I'll test it.

Hello Elmor,

I recently ordered a PNY card, using the NCP81610 pwm controller -> https://www.onsemi.com/products/power-management/dc-dc-controllers-converters-regulators/controllers/ncp81610

I was eager to start my modding escapades, and just now ordered your EVC2SX. Damn, to late I realised it doesn’t support that pwm controller yet. Any chance you can add support for it perhaps? It is quite common on many cards nowadays, and has an I2C bus.

Looking forward to your feedback.

Cheers,

Beano

Hello Phillip. I can add support for this controller, however the key reason why it has not been done yet is because this controller according to its datasheet does not support voltage control over I2C. It does offer some adjustments like switching frequency and OCP/OVP control and monitoring of output voltage/current. Let me know if you still want me to add a profile for it with this level of functionality.

An alternative method for voltage control might be to use the EVC2SX VMOD header and through that adjust the voltage at the controller REFIN pin which is the voltage setting for the output. More details on that further down in this thread: https://www.elmorlabs.com/index.php/forum/topic/evc2-vmod1-header-tutorial/
