Texas Instruments UCD3040 Fully Programmable Digital Power Controller with Four Feedback Loops and Eight DPWM Outputs UCD3040RGCT

The UCD3040RGCT is a fully programmable digital power controller designed for high-performance power conversion applications. It features four independent voltage feedback loops and eight high-resolution digital pulse-width modulation (DPWM) outputs, allowing for flexible configuration in various isolated and non-isolated DC-to-DC topologies. The device operates with a 31.25 MHz ARM7 processor and includes a 32 KB program flash memory, 2 KB data flash memory, and 4 KB data RAM, enabling complex control algorithms and real-time monitoring. This controller supports multiple control modes, including voltage-mode, average-current-mode, and resonant-mode control, making it suitable for a wide range of applications such as isolated AC-to-DC and DC-to-DC power supplies. It also incorporates a dedicated high-speed error analog-to-digital converter for each feedback loop, ensuring precise control and monitoring. The UCD3040RGCT operates over an extended temperature range of -40°C to 125°C, making it suitable for demanding environments. Its comprehensive fault protection features and communication peripherals, including PMBus and UART, enhance its usability in advanced power management systems.
