FEATURES

DESCRIPTION

•

1.0% Output Current Accuracy (0°C to +100°C)

The LM10011 is a precision, digitally programmable

•

1.25% Output Current Accuracy (–40°C to

device used to control the output voltage of a DC/DC

+125°C)

converter. The LM10011 outputs a DC current

•

Input Voltage Range: +2.97V to +5.5V

proportional to a 6-bit or 4-bit input word. By

connecting the IDAC_OUT pin to the feedback node

•

Pin Selectable VID Format (6/4 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 3mm x 3mm Footprint, 0.5mm 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

APPLICATIONS

range of 0 to 56.4µA with 4 bits of resolution. The

•

Broadband, Networking, and Wireless

MODE pin allows programming of the device through
