The LM10011 is a precision, digitally programmable device used to control the output voltage of a DC/DC converter. The LM10011 outputs a dc current proportional to a 6-bit or 4-bit input word. By connecting the IDAC_OUT pin to the feedback node of a regulator, the regulator output voltage can be adjusted to a desired range and resolution set by the user. As the input word counts up, the output voltage is adjusted higher based on the values of the feedback resistors in the converter.
The current from the IDAC_OUT pin on start-up is programmable by an external resistor to cover the range of 0 to 56.4 µA with 4 bits of resolution. The MODE pin allows programming of the device through a 4-bit parallel VID interface or through a 6-bit interface consisting of upper and lower 3-bit VID codes. The LM10011 is specifically designed to program a wide variety of Texas Instruments DC/DC converters for VID (Voltage Identification) applications.

This reference design aims to supply the AVS core supply (CVDD) in the Keystone Multicore DSPs, mainly the C66x series. The C66x series uses SmartReflex technology to enable the DSP to control its supply voltage. In order to meet this requirement, this design combines a Synchronous Buck Converter (...)
The K2E requires the use of AVS SmartReflex control for the CVDD core voltage. This design provides method of generating the proper voltage without the need for any software. The circuit is currently implemented on the XEVMK2EX.
