LM10011
SNVS822A –DECEMBER 2012–REVISED NOVEMBER 2014
LM10011 6/4-Bit VID Programmable Current DAC for Point of Load Regulators with
Adjustable Start-Up Current
1 Features 3 Description
The LM10011 is a precision, digitally programmable
1
• 1.0% Output Current Accuracy (0°C to 100°C)
device used to control the output voltage of a DC/DC
• 1.25% Output Current Accuracy (–40°C to 125°C)
converter. The LM10011 outputs a dc current
• Input Voltage Range: 2.97 V to 5.5 V
proportional to a 6-bit or 4-bit input word. By
connecting the IDAC_OUT pin to the feedback node
• Pin Selectable VID Format (6- or 4-bit)
of a regulator, the regulator output voltage can be
• 16 Selectable Start-Up Currents
adjusted to a desired range and resolution set by the
• Precision Enable to Support Custom UVLO
user. As the input word counts up, the output voltage
is adjusted higher based on the values of the
• SON-10 3-mm × 3-mm Footprint, 0.5-mm Pitch
feedback resistors in the converter.
• Footprint Compatible with the LM10010
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
• Broadband, Networking, and Wireless
MODE pin allows programming of the device through
Communications
a 4-bit parallel VID interface or through a 6-bit
• Notebook Power Solutions
interface consisting of upper and lower 3-bit VID
codes. The LM10011 is specifically designed to
• Portable Instruments
program a wide variety of Texas Instruments DC/DC
• Battery-Powered Equipment
converters for VID (Voltage Identification)
• Powering Digital Loads with a 6-bit or 4-bit, 4-Pin
applications.
