M1355
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.
FEATURES
CMOS technology.
3 output channels for RGB LED lamps.
Output current invariant to load voltage change.
8-bits luminance data with PWM current output.
Built-in buffers for cascading clock, CK, SDA,STB to other devices.
APPLICATIONS
LED Decorative Lighting.
PWM Signal Generator.
Keypad backlighting
