Supertex constant-current LED drivers deliver fixed 100 mA output

June 23, 2006
Date Announced: 23 Jun 2006 NEW CONSTANT CURRENT DRIVERS FROM SUPERTEX DELIVER FIXED 100mA OUTPUT-- CL6 & CL7 Are Ideal for Up To 24V/48V Applications SUNNYVALE, Calif., June 22, 2006 – Supertex, Inc. (NASDAQ: SUPX), a recognized leader in high voltage analog and mixed signal integrated circuits (ICs), today introduced CL6 and CL7, two linear, constant current, LED drivers with fixed output currents of 100mA. The devices are ideally suited for applications using 24V/48V inputs.Both ICs feature built-in reverse polarity protection as well as over-temperature protection. With maximum ratings of 90V, the ICs are able to withstand transients without any additional transient protection circuitry when used as recommended. The CL7 also features an active low enable input pin that allows logic level control of the LED for on/off or PWM dimming control.“The introduction of CL6 and CL7 further broadens Supertex’s family of high performance LED drivers,” states Ahmed Masood, Vice President of Marketing for Supertex. “CL6 and CL7 are simple, easy-to-use devices that provide constant current output and low EMI noise in 24V/48V LED lighting applications.”CL6 is available in D-PAK (CL6K4-G) and three lead TO-220 (CL6N5-G) packages. CL7 is available in a power SO-8 (CL7SG-G) package. They are all Green and RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$0.93 each for CL6K4-G, US$0.99 each for CL6N5-G, US$1.12 each for CL7SG-G, all in 1K quantities.About SupertexSupertex, Inc. is a publicly held mixed signal semiconductor manufacturer, focused on high voltage interface products for use in the telecommunications, networking systems, medical, automotive and industrial electronics industries.
