VID Voltage Programmer for Point of Load Regulator
General Description
The LM10010 is a precision, digitally programmed device
used to control the output voltage of a DC/DC converter. The
LM10010 outputs a DC current inversely proportional to a 6-
bit input word. This current DAC output connects to the feed-
back pin of a regulator in order to adjust its output voltage to
a desired range and resolution set by the user. As the 6-bit
word counts up, the output voltage is adjusted higher based
on the setting of the feedback resistors in the converter.
The LM10010 is designed to program point of load regulators
with adjustable resistor feedback networks for VID (Voltage
Identification).
Features
■ 3% output current accuracy (-40°C to +125°C)
■ Input voltage range: 3V to 5.5V
■ 6-bit current DAC that connects directly to the feedback
node of an external regulator to provide output voltage
control
■ Precision enable to support custom UVLO
■ LLP-10 3 mm x 3 mm footprint, 0.5 mm pitch
Applications
■ Broadband, networking, and wireless communications
■ Notebook and palmtop computers, PDAs
■ Portable instruments
■ Battery-powered equipment
■ Powering digital loads with a 6-bit, 4 pin VID interface
