GENERAL DESCRIPTION

The M1355 is a 3-channel PWM enabled current sink driver for RGB LED or display applications. M1355 includes a serial

buffer and data latches which convert serial input data into parallel output format, and built-in oscillator for PWM functioning.

Data and clock buffer outputs are designed for cascading another chip. It is easy to be designed in applications that need mixing

RGB light sources for multi-color output. The output current is determined by an external resistor and the brightness control code,

both set by users.
