Texas Instruments introduced the UCD3138 digital power management controller

Texas Instruments (TI) announced the availability of can be configured for the AC / DC and isolated DC / DC power applications optimized integration of digital power management controller, to further expand its analog and digital power management solutions rich. The UCD3138 ways to design an innovative, effective for the server, telecom rectifiers and power DC / DC module used in a wide variety of power supply topologies to improve power density and reliability.
Assist in the design of digital control functions to further leverage its power system performance, including hardware design reuse across multiple platforms, and adjust the performance and control parameters for each application, thereby speeding time to market. To achieve this goal, UCD3138 seamless integration in a small 6 mm x 6 mm package with a powerful 32-bit microprocessor, high-speed high-precision data converters, multiple programmable hardware control circuit and a communication engine.

The UCD3138 enhance the peak and light load efficiency. The device can improve the efficiency of control functions, including soft switch control of the synchronous FET, dynamic phase switching, dynamic frequency scaling and dynamic mode switch; support all isolated power supply topologies: The controller supports single-phase two-phase interleaved or no bridge power factor correction, hard switching full-bridge phase-shift full-bridge resonant LLC and other topologies.

Integration of all the basic protection features. The components can be implemented peak current mode control, cycle by cycle peak current limit, high-speed input voltage feedforward (feed-forward) as well as overvoltage, overcurrent and overtemperature protection. Easy-to-use GUI development tool, designers can easily get several digital power development tools, including feature-rich voltage evaluation modules, development kits, reference designs, application firmware source code, the programmer manual and Code Composer Studio software development environment.

TI's Fusion Digital Power Designer, a graphical user interface (GUI) software tools not only a high degree of flexibility to configure power parameters, but also provide telemetry (telemetry), log (the logging), and communication functions. Card with open-loop (open-loop) evaluation module such as a variety of hardware design tools are available for most customers.

In addition, TI also offers easy-to-use development kits and reference designs, including universal input 400 to Vout AC / DC PFC Development Kit Development Kit UCD3138PFCEVM-026 can be configured in single, two-phase interleaved and non-bridge topology; 400 Vin / 12 to Vout of the DC / DC phase shift full bridge UCD3138PSFBEVM-027; 400Vin/12 to Vout of the DC / DC half-bridge resonant LLC UCD3138LLCEVM-028; 48 Vin/12 to Vout of the DC / DC hard switching full-bridge UCD3138HSFBEVM-029 Development Kit. Universal input 12 to Vout 600 W AC / DC reference design (PFC plus LLC, and the PFC plus phase-shift full-bridge) with Vin/12 48 to Vout 1/8 brick DC / DC reference design (hard switching full-bridge).

TI's complete analog and digital power management and MCU optimization type solutions to fully meet all the digital power supply design requirements. TI's digital power controller for isolated power UCD3K series, as well as for non-isolated point of load the design UCD9K series. TI analog protection system management controller (such as the LM5064 and LM5066 and TPS40400 and TPS40422 analog PWM controller, etc.) to integrate the PMBus digital communication interface, which provides a configurable, telemetry, and monitoring capabilities. In addition, TI's comprehensive programming TMS320F28x MCU also supports a variety of power and energy-related applications, provide a variety of functions and high performance.
