Versatile controller for all major topologies, TI unveils the UCD3138064 for AI power systems

As AI data centers and new energy infrastructure scale up, the need for intelligent, highly integrated power management is peaking. TI’s new UCD3138064 digital power controller steps up as an enhanced successor to the UCD3138 series, bridging the gap between analog and dedicated digital control. It handles nearly any power topology—AC/DC, isolated DC-DC, or PFC—with ease, serving as a one-stop powerhouse for voltage regulation, protection, and communication in high-end digital power supply designs.

The UCD3138064 is engineered for performance and reliability. Its 32-bit ARM core manages complex algorithms, while the 64KB dual-partition Flash is a game-changer for AI servers, enabling zero-downtime firmware updates to ensure continuous operation. It offers pin-to-pin compatibility with the standard UCD3138, making it an easy upgrade for legacy designs. On-chip hardware digital PID loops and ultra-precise DPWM modules support advanced soft-switching topologies, paired with full-suite fault protection and light-load energy-saving modes. Plus, with a wide array of interfaces—SPI, dual I2C, PMBus, and dual UART—it ensures seamless, low-latency integration with modern rack management systems.

By replacing "rigid" dedicated controllers with a fully programmable, multi-topology solution, TI’s UCD3138064 allows developers to streamline their portfolio across everything from AI server PSUs to EV charging infrastructure. This unified approach cuts BOM costs, simplifies code management, and accelerates time-to-market, providing a vital chip-level paradigm for the industry's push toward efficient, intelligent, and sustainable power architectures.
