The SC606 is a very high efficiency charge pump white/color LED driver from the mAhXLifeTM family of products. It is optimized for Li-Ion battery applications. The LED current is regulated to a value configured by the user through an I2C compatible serial interface. LED outputs are current-matched for consistent LED brightness. Up to 6 LEDs are controlled in three zones for brightness control in multiple displays. The 6 LED outputs are divided into 3 pairs of LEDs. Each pair has current that is programmable independent of the other pairs. Any combination of LEDs may be turned on using the serial interface. The SC606 also has a float detect feature that disables any current driver during normal operation when an open-load condition is detected. Patented low noise switching circuitry and constant output current allow the use of extremely small input and output capacitors.
