Semtech Intros Software-Controlled SC606 Driver

February 09, 2005 by Jeff Shepard

Semtech Corp. (Camarillo, CA), a producer of analog and mixed-signal semiconductors, announced its SC606 charge pump driver, which is designed to deliver consistent LED brightness and extended battery life in advanced lithium-ion battery-powered, hand-held devices.

The SC606 is a member of Semtech’s fractional charge pump family, and is based on the company’s patented mAhXLife™ technology. The SC606 can power six LEDs in a configuration that is suitable for advanced PDA, cell phone or other multi-function devices. The output range for each pair can be adjusted from 0 mA to 32 mA with 500 µA resolution, and tight current regulation is guaranteed for a total device output up to 120 mA. The SC606 leverages the mAhXLife technology to deliver current accuracy of ±6.5% over a wide range of input voltages. Typical current accuracy is 2%. The SC606 delivers more than 90% power efficiency with a built-in, three-mode, self-regulating feature that adjusts the voltage conversion ratio based on input-voltage levels.

The SC606 is available immediately in production quantities, and is priced at $1.30 each in 1,000-piece lots. The device is available in a 4 mm x 4 mm MLP-16 package.
