Texas Instruments' dual-output, multi-phase Fusion Digital Power(TM) controller provides intelligent point-of-load design

Full-featured graphical user interface eases designs, helps speed time-to-market

DALLAS, April 1 /PRNewswire/ -- Expanding the company's line of Fusion Digital Power controllers, Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced a new dual-output, multi-phase synchronous buck controller that can support various point-of-load configurations. The UCD9220 device provides 250 picoseconds of pulse-width-modulation, a 2-MHz switching frequency and high DC conversion ratios, while maintaining stable operation. The flexible controller meets complex power design requirements in telecommunications, server, data storage and industrial test and measurement applications. Designers can use the Digital Power Designer, a full-featured graphical user interface, to configure the device easily and speed time-to-market. For product details see www.ti.com/ucd9220-pr.

Key features/benefits of the UCD9220

    --  Flexible digital power control enables full loop compensation, including
        on-linear control for enhanced transient performance and system
        reliability
    --  Phase current balancing ensures uniform power dissipation
    --  Configurable switching frequency up to 2 MHz increases bandwidth and
        allows use of smaller passive components to save board space
    --  Optimized power management features to enhance performance, such as
        PMBus(TM)-configurable voltage setting, sequencing, power-up and
        power-down timing and fault response
    --  250 picoseconds of pulse-width-modulation allows for a high switching
        frequency and high conversion ratios while maintaining stable operation

Availability and pricing

The UCD9220 is available in a QFN-48 package and is priced at $2.65 in quantities of 1,000. The UCD9220 evaluation module will be available in late second quarter 2009.
