Texas Instruments Showcases Latest Technologies At Digital Power ForumSeptember 15, 2008 by Jeff Shepard
Texas Instruments Inc. (TI) has unveiled its latest solutions and product demonstrations for ac to dc-dc point-of-load applications at the 2008 Digital Power Forum. TI experts will also present a variety of technical papers on digital power at the conference.
The UCD9240 pulse-width modulation controller, now in volume production, digitally manages up to four independent outputs and up to eight phases. The UCD92K family of controllers supports switching frequencies up to 2 MHz with up to 1mV resolution, enabling dc conversions down to 500mV from a 16V input source.
The controllers are configured using an easy-to-use Fusion Digital Power™ Designer tool. The tool, which is free and downloadable, is said to simplify the development process and to improve time-to-market by allowing the designer to easily configure many power supply parameters, including voltage and current thresholds with selectable fault response; supply voltage sequencing; monitoring; soft start/stop; tracking; margining; control loop response; phase management and fan control.
TI also introduced three complementary digital PowerTrain™ modules to further simplify dc-dc converter design by providing a high-degree of space saving component packaging and convenience. The PTD08A006W, PTD08A010W, PTD08A020W and 6-A, 10-A, 20-A modules integrate the inductor, MOSFETs and the UCD7230 driver. Additionally, reference designs using integrated driver/MOSFET technology are available for applications that require ultra-high conversion efficiencies.
