General Description
MBI1009 is a 3-channel current sink driver for RGB LED lamps. It is easy to be designed in applications that need
mixing RGB light sources for multi-color output. MBI1009 contains a serial buffer and data latches which convert
serial input data into parallel output format. At MBI1009 output stage, three regulated current ports are designed to
provide uniform and constant current sinks for driving LEDs within a large range of Vf variations. The output current
is determined by an external resistor and the brightness control code, both set by users.
MBI1009 provides users with great flexibility and device performance. Users may adjust the output current from 5
mA to 40 mA, which gives users flexibility in controlling the light intensity of LEDs. MBI1009 guarantees to endure
maximum 17V at the output port.
