IS32FL3761
33×12 DOTS MATRIX LED DRIVER
GENERAL DESCRIPTION
The IS32FL3761 is a general purpose 33 × n (n=12~2) LED Matrix programmed via 1MHz I2C or 12MHz SPI compatible interface. Each LED can be dimmed individually with 12-bit/8+4-bit/8-bit/6+2-bit PWM data and each color sink can have 8-bit DC scaling data which allowing 256 steps of linear PWM dimming and each color sink has 256 steps of DC current adjustable level and precision for smooth LED brightness control. The output current of each channel is designed to be 30mA, which can be adjusted by 8-bit global control register and the SL registers. Proprietary algorithms are used in IS32FL3761 to minimize power bus noise caused by passive components on the power bus such as MLCC decoupling capacitor.
