8 Application and Implementation
SNVS822A – DECEMBER 2012 – REVISED NOVEMBER 2014
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
LM10011 is a precision, digitally programmable device used for controlling the dc-dc converter output voltage.
The LM10011 GUI design tool is available at www.ti.com/product/LM10011 and can be used to program any
voltage regulator output to a desired range and resolution. The GUI enables changing the output voltage of the
on-board POL based on direct user input. It is also able to assist the power designer in selecting the correct
external components needed for any given application.
8.2 Typical Application
In this example, an LM21215A-1 is used as the voltage regulator and the desired range of output voltage
operation is 0.7 V to 1.1 V. The LM10011 can provide control of the output voltage within this range with 6 bits or
4 bits of resolution. For this example, the 400 mV of voltage range translates to a VOUT_LSB of 400 mV / 63 = 6.4
mV (26.7 mV in 4-bit mode) at the regulator output. In this calculation, 1% resistor values are used. A schematic
for this example is shown in Figure 12.
