The Texas Instruments UCD3138128APFCR is a highly-integrated digital controller designed for isolated power applications. This device offers 128 kB of Program Flash memory, supporting firmware updates without shutting down the power supply. It includes advanced features such as dual memory image support for 'on the fly' firmware updates and synchronous rectifier dead time optimization.
The controller boasts a 16 MSPS Error A/D Converter (EADC) with configurable resolution and hardware-based averaging. It also provides up to 8 high-resolution Digital Pulse Width Modulated (DPWM) outputs with precise pulse width, frequency, and phase resolution. The UCD3138128APFCR supports various control modes including voltage, average current, and peak current mode control, as well as constant current and constant power operation.
Packaged in an 80-TQFP (12x12 mm) surface mount configuration, this controller operates from -40°C to 125°C. It includes multiple communication ports, fault protection options with analog and digital comparators, and cycle-by-cycle current limiting, making it suitable for demanding power management designs.
