More Information

The UCD3138 family is a digital power supply controller from Texas Instruments offering superior levels of integration and performance in a single chip solution. The UCD3138x, in comparison to Texas Instruments UCD3138x digital power controller offers 64 kB of program Flash memory in UCD3138A64 (128 KB in UCD3138128) and additional options for communication such as SPI and a second I2C port. The availability of program Flash memory in multiple 32 kB banks enables designers to implement dual images of firmware (e.g. one main image + one back-up image) in the device and provides the option to execute from either of the banks using appropriate algorithms. It also creates the unique opportunity for the processor to load a new program and subsequently execute that program without interrupting power delivery. This feature allows the end user to add new features to the power supply in the field while eliminating any down-time required to load the new program.
