Overview
The LM10011SDX/NOPB, produced by Texas Instruments, is a precision, digitally programmable device designed to control the output voltage of DC/DC converters. This component is particularly useful in point of load regulator applications, allowing for precise adjustment of the output voltage through a 6-bit or 4-bit VID (Voltage Identification) interface. The LM10011 features a current DAC (Digital-to-Analog Converter) that injects a precision current into the feedback node of a regulator, thereby adjusting the output voltage. The device is available in a compact 10-pad SON-10 package with a 3 mm x 3 mm footprint.
