Texas Instruments UCD3138064A
The UCD3138064A is a digital power supply controller from Texas Instruments offering superior levels of integration and performance in a single-chip solution. The UCD3138064A, in comparison to Texas Instruments UCD3138 digital power controller (Section 3), offers 64 kB of program Flash memory (vs 32 kB in UCD3138) and additional options for communication such as SPI and a second I2C port. The availability of 64 kB of program Flash memory in 2-32 kB banks, enables the designers to implement dual images of firmware (e.g.| Part No. | UCD3138064A |
