IS31FL3199-QFLS2-EB ISSI

9-CHANNEL LIGHT EFFECT LED DRIVER DESCRIPTION RECOMMENDED EQUIPMENT IS31FL3199 is a 9-channel light effect LED driver 5.0V, 2A power supply which features two-dimensional auto breathing mode and an audio modulated display mode. It has One ABSOLUTE MAXIMUM RATINGS Shot Programming mode and PWM Control mode for RGB lighting effects. The maximum output current 5.5V power supply can be adjusted in 8 levels (5mA~40mA). Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. FEATURES 2.7V to 5.5V supply voltage PROCEDURE I2C interface, automatic address increment The IS31FL3199 evaluation board is fully assembled function and tested. Follow the steps listed below to verify Three groups RGB, single color LED breathing board operation. system-free pre-established pattern 9 independently controlled automatic and Caution: Do not turn on the power supply until all connections are completed. semiautomatic breathing system-free pre- established pattern 1) Short JP1 to connect by board MCU (default 9 independently controlled outputs of 256 PWM short). steps 2) Connect the 5VDC power to the connector 8 levels programmable output current (TP1&TP2) (Skip this step if use Micro-USB as power input). Audio mode with AGC function 3) Turn on the power supply/Plug in the Micro USB Cascade for the synchronization of chips Pay attention to the supply current. If the current Over-temperature protection exceeds 1A, please check for circuit fault. QFN-20 (3mm 3mm) package EVALUATION BOARD OPERATION QUICK START The IS31FL3199 evaluation board has five display modes. Press K1 to switch configurations. 9 lamps breathe at the same time 1) 2) The RGB monochromatic breathes 3) RGB audio mode 9 lamps breathe one by one 4) 9 lamps audio mode 5) Note: IS31FL3199 solely controls the FxLED function on the evaluation board.

If it is set to open, firmware updates. First download the latest Arduino the MCU s SDB, SCL, SDA and CLK pin will be high Integrated Development Environment IDE (1.6.12 or impedance (open-drain) and external control is greater) from www.arduino.cc/en/Main/Software. allowed. Also download the Wire.h library from www.arduino.cc/en/reference/wire and verify that pgmspace.h is in the directory program Files(x86)/Arduino/hardware/tools/avr/avr/include/a vr/. Then download the latest IS31FL3199 test firmware (sketch) from the Lumissil website
