TI's Dual-Output, Multi-Phase Fusion Digital Power™ Controller

 2009-04-15
Full-featured graphical user interface eases designs, helps speed time-to-market

Expanding the company's line of Fusion Digital Power controllers, Texas Instruments Incorporated 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 PMBusTM-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
