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 feedback 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).
