VID Interface

3 Description

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.
