lyst Semiconductor, Inc. announced that its CAT4201, 7W buck LED driver has been named to the EDN Magazine's list of Hot 100 Products of 2007.
The CAT4201 was selected one of nine hot products in the "Power Semiconductors and ICs" category, which includes leading analog semiconductor suppliers.
About the CAT4201 LED Driver
The first device in a new family of buck converters, the CAT4201 is optimized for driving high-brightness, 350mA LEDs at up to 94 percent efficiency. The device incorporates Catalyst's patent-pending switching control scheme, which reduces system complexity and improves efficiency by providing better inductor control and eliminating the need for a dedicated heat sink. Traditionally, LEDs from 12V or 24V buses have been driven by linear regulators, which generate a significant amount of heat, resulting in the need for a dedicated heat sink and, therefore, a very large TO263 package. The patented architecture and small package size (TSOT-23) of the CAT4201 offer a simpler and significantly smaller alternative to linear regulators in high-power LED lighting applications.
