Smart PWM Controller from STMicroelectronics Increases Efficiency and Reduces Costs for Notebook Power Supplies

STMicroelectronics announced an innovative current-mode primary controller IC designed to build single-ended switching power converters. The L6668's advanced functions make it one of the most innovative and efficient controllers available for power supplies.

Current-mode primary controller IC includes advanced standby function, high-voltage start-up with 700V capability, and dedicated PFC interface

Ideally suited for use in high-end AC/DC adapters and chargers for notebook or laptop PCs, the versatility of the L6668 current-mode PWM controller also makes it suitable for power supplies of set-top boxes, DVD players, low-end LCD TVs and other digital consumer equip-ment. In addition, excellent energy-saving features make the IC a good choice in low-power auxiliary converters used in high-end LCD and plasma-based TVs, desktop PCs and server power supplies.

The IC combines a number of functions able to change the way the device works to optimize power processing under all operating conditions with excellent electrical characteristics. This combination allows development of robust and energy-efficient designs.
