LED Driver
Semtech announces the SC606, a charge pump white/color LED driver for up to six LEDs. The dual U.S.-patented driver is designed to deliver consistent LED brightness and extended battery life in advanced Lithium Ion (Li-Ion) battery-powered handheld devices. The SC606 can power six LEDs in a configuration that is suitable for advanced PDA, cell phone, or other multifunction devices. The six LEDs are divided into three pairs, each of which can be programmed independently from the others. Output range for each pair can be adjusted from 0 to 32 mA with 500 uA resolution, and tight current regulation is guaranteed for a total device output up to 120 mA. LED brightness levels for each pair can be controlled via an Inter-Integrated Circuit (I2C) serial bus that allows designers to control dimming, brightness, or blinking LED applications.
