TPS53679, TPS53659, TPS53622 are Intel™ VR13 Serial VID (SVID)-compliant power supply controllers that have programmable parameters. This guide also applies to proprietary footprint devices TPS53678, TPS53658 TPS53655, as well as TPS53681, even though it is not an Intel power controller. The PMBus interface configures the parameter values which are stored into non-volatile memory (NVM) as new boot-up default values. This guide gives a tutorial on NVM programming, and the tools TI provides for the programming process. This guide applies to all the devices in the TI VR13 controller family.
