The UCD3138A64PFC from Texas Instruments is a highly-integrated digital controller designed for isolated power applications. This device offers advanced control capabilities with up to 16 MSPS Error A/D Converter (EADC) and a 14-bit Effective Reference DAC.
Key features include 64 kB of Program Flash memory, with banks supporting execution from one bank while programming another, enabling firmware updates without shutting down the power supply. It provides digital control for up to 3 independent feedback loops and utilizes dedicated PID-based hardware for non-linear control.
The controller supports 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 can operate at switching frequencies up to 2 MHz. The device is housed in an 80-TQFP (12x12 mm) package and supports surface mount.
With features like burst mode, ideal diode emulation, synchronous rectifier support, and low IC standby power, the UCD3138A64PFC is suitable for high-efficiency and light-load management in power supply designs. It also includes comprehensive fault protection options with 7 analog and 4 digital comparators.
