UCD3138064RMHR

The UCD3138064RMHR from Texas Instruments is a highly integrated digital controller designed for isolated power applications. This device features 64kB of program flash memory, allowing for flexible firmware updates without shutting down the power supply. It supports execution from one bank while programming another, enhancing operational efficiency.

The controller operates within a voltage range of 3V to 3.6V and can function across a wide temperature range from -40°C to 125°C. It provides advanced control capabilities, including digital control of up to 3 independent feedback loops with dedicated PID-based hardware. The device includes a high-speed error analog-to-digital converter (EADC) with configurable resolution and hardware-based averaging. It also offers up to 8 high-resolution digital pulse width modulated (DPWM) outputs with precise pulse width and frequency resolution.

Designed for high efficiency and light load management, the UCD3138064RMHR incorporates features like burst mode and ideal diode emulation. It supports various control modes such as voltage, average current, peak current, constant current, and constant power. The controller is available in a 40-WQFN (6x6 mm) surface mount package, suitable for various power supply designs.

With its rich fault protection options, including analog and digital comparators, cycle-by-cycle current limiting, and programmable blanking time, the UCD3138064RMHR ensures robust operation. Its additional communication ports compared to the UCD3138 family, including SPI and I2C, provide enhanced connectivity for complex systems.
