Digital Controllers Enhance Power System Design

Designed to enhance the performance and lifetime of current power systems, the Fusion UCD9K, UCD8K, and UCD7K series digital controllers support power supply systems from ac-line to point-of-load applications. The UCD9K devices integrate unique power peripherals and can close one or more feedback loops while providing communications and supervisory functions. They achieve digital PWM resolutions up to 150 ps. Combining digital and analog attributes, the UCD8K and UCD7K devices offer digital control support by integrating power management functionality best 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. Prices for the UCD9K, UCD8K, and UCD7K start at $4.95, $1.99, and $0.99 each/1,000, respectively. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
