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.
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-configurable voltage setting, sequencing, power-up and power-down timing and fault response;
250 picoseconds of pulse-width-modulation allow 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.
