Guest barbonenet Posted March 5, 2014 Share Posted March 5, 2014 hi John it's possible to work on this regulator? i see in datasheet pin 4 and 5 are sda scl! if doesn't it work, i damage vga? thanks Quote Link to comment Share on other sites More sharing options...
elmor Posted March 14, 2014 Share Posted March 14, 2014 (edited) hi John it's possible to work on this regulator? i see in datasheet pin 4 and 5 are sda scl! if doesn't it work, i damage vga? thanks Let me check the datasheet, you can solder the cables without any worries. The software has to be updated to support this VRM controller though. edit: The available datasheet doesn't disclose anything about how the serial interface works, and states "The device manages serial BUS communication to program power management functionalities as well as monitoring.". It's possible it does not support voltage control over serial bus at all. Also the output voltage seems limited to 1.35V, even with full access to its internals.

CL3P20 Posted December 3, 2014 Share Posted December 3, 2014 I can confirm - with lowered OCP the circuit will output ~1.38v under load after mods Quote Link to comment Share on other sites More sharing options...
