Product Summary

The SC6200 is a multi-purpose LED driver with eight identi-cal, independently controlled current sinks. Each current sink can drive an LED by connecting the LED’s anode to the system power supply and the cathode to the current sink input pin. Any combination of outputs can be enabled or disabled for optimal design flexibility. The applications of the SC6200 include LCD backlighting LED driver, Multicolor and RGB LED driver, General purpose current sink array, General purpose digital output (open-drain) expander and Auto-focus voice-coil driver.
