TI Unveils UCD9K/8K/7K Series Fusion Digital Power Devices

March 03, 2005 by Jeff Shepard

Texas Instruments Inc. (TI, Dallas, TX) announced its new Fusion Digital Power™ solutions, including the UCD9K, UCD8K and UCD7K Series, which enhance the performance and lifetime of today's power systems. TI's UCD9K, UCD8K and UCD7K Series support power supply systems from ac-line to point-of-load applications, including telecommunications, uninterruptible power supplies (UPS), computer servers and data-centric power systems.

The UCD9K high-resolution, digital power controllers with integrated power peripherals have the ability to close one or more feedback loops and provide communications and supervisory functions. Achieving up to 150 picoseconds digital pulse-width modulation (PWM) resolution, the digital signal processor (DSP)-based and microcontroller-based controllers contribute in several areas of complex power conversion, including multi-phase control, non-linear control, load-sharing and predictive failure.

The UCD8K and UCD7K devices offer digital control support by integrating key power management functionality performed by analog circuits. The UCD7K devices are MOSFET drivers that interface the digital power controller to the power stage and provide protection and bias supply management. The UCD8K controllers integrate the UCD7K devices with a digitally controlled analog PWM controller to close the feedback loop.

Samples of the Fusion Digital Power solutions are currently available. Volume production of the UCD9K, UCD8K and UCD7K is expected in the next six months. Suggested pricing in quantities of 1,000 units starts at $4.95 for the UCD9K devices, $1.99 for the UCD8K controllers and $0.99 for the UCD7K family.
