The UCD3138064RGCR from Texas Instruments is a highly-integrated digital controller designed for isolated power applications. This device offers 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.
Key electrical specifications include an operating voltage range of 3V to 3.6V and an operating temperature range of -40°C to 125°C. The controller features up to 8 high-resolution digital pulse width modulated (DPWM) outputs with 250-ps pulse width resolution and 4-ns frequency and phase resolution. It also includes a 16-MHz error A/D converter with configurable resolution and hardware-based averaging up to 8x.
Packaged in a 64-VQFN (9x9 mm) with an exposed pad, the UCD3138064RGCR is suitable for surface mount applications. The device provides digital control for up to 3 independent feedback loops and includes dedicated PID-based hardware for non-linear control. It offers various control modes such as voltage, average current, and peak current mode control, as well as constant current and constant power operation.
With features like burst mode, ideal diode emulation, and synchronous rectifier soft on/off, the controller is optimized for high efficiency and light load management. It also incorporates robust fault protection with 7 analog and 4 digital comparators, cycle-by-cycle current limiting, and programmable blanking time.
