LM10010SD/NOPB

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). The LM10010 is a precision current DAC used for controlling any point of load regulator with an adjustable resistor feedback network. Four communication lines are used to write to a 6-bit IDAC value. The output of the IDAC is used to send current to the feedback node of a regulator, adjusting the output voltage. With this method, it is possible to precisely control the output voltage of the regulator. An enable pin (EN) is provided to allow for a reduced quiescent current when not in use. Also, the VDD line is monitored so that an under-voltage event will shut down the device. The device is available in a 10-pad No-Pullback Leadless Leadframe Package (WSON-10). The LM10010 can be used in numerous applications with regulators from 3.0V to 5.5V supplies.
