Expanding its broad portfolio of analog and digital power management solutions, Texas Instruments Incorporated (TI) introduced the industry's most integrated and configurable digital power management controller optimized for AC/DC and isolated DC/DC power supply applications. The UCD3138 gives designers an innovative path to increase power density and reliability in a broad range of power supply topologies used in servers, telecom rectifiers and high-power DC/DC modules.
Digital control capabilities allow designers to do more with their power systems, including re-usability of hardware designs across multiple platforms and the versatility to fine-tune performance and control parameters for each application, allowing faster time to market. To enable this, the UCD3138 combines a powerful 32-bit microprocessor, high-speed precision data converters, multiple programmable hardware control loops and various communication engines in a small 6-mm x 6-mm package.
Key Features " Boosts peak and light load efficiency: The device features several control functions to increase efficiency, including sync-FET soft on-off control, dynamic phase shedding, dynamic frequency adjustment and dynamic mode switching " Supports all isolated power supply topologies: The controller supports single-phase, two-phase interleaved, or bridgeless power factor correction, hard-switching full-bridge, phase-shifted full-bridge, resonant LLC and other topologies. " Integrates all essential protection features: The device implements peak current mode control, cycle-by-cycle peak current limiting, high-speed input voltage feed-forward, over-voltage, over-current and over-temperature protection.
Designers will have easy access to several digital power development tools including full-voltage and feature-rich evaluation modules, development kits, reference designs, application firmware source code, programmer's manuals and the Code Composer Studio™ software development environment. TI's Fusion Digital Power Designer graphical user interface (GUI) software tool provides flexible configuration of key power parameters, as well as telemetry, logging, and communication functions. A broad range of hardware design tools, such as control card and open-loop evaluation modules, are available to select customers.
The UCD3138 is sampling now with volume production expected in the second quarter. It comes in a thermally enhanced 40-pin, 6-mm x 6-mm QFN package and supports a temperature range of -40C to 125C.
Suggested resale pricing is $2.70 in 1,000-unit quantities. A 64-pin, 9-mm x 9-mm QFN version of the UCD3138 is priced at $4.10 in 1,000-unit quantities.
