The LM10011SD/NOPB is a 6/4-bit VID Programmable Current DAC for point of load regulator with adjustable start-up current. The LM10011 is a precision, digitally programmable device used to control the output voltage of a DC/DC converter. It outputs a dc current proportional to a 6-bit or 4-bit input word. By connecting the IDAC_OUT pin to the feedback node of a regulator, the regulator output voltage can be adjusted to a desired range and resolution set by the user. As the input word counts up, the output voltage is adjusted higher based on the values of the feedback resistors in the converter. The current from the IDAC_OUT pin on start-up is programmable by an external resistor to cover the range of 0 to 56.4 μA with 4 bits of resolution. The MODE pin allows programming of the device through a 4-bit parallel VID interface or through a 6-bit interface consisting of upper and lower 3-bit VID codes.
