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.
