IS31FL3199

IS31FL3199 9-CHANNEL LIGHT EFFECT LED DRIVER January 2012 GENERAL DESCRIPTION IS31FL3199 is a 9-channel light effect LED driver which features two-dimensional auto breathing mode and an audio modulated display mode. It has One Shot Programming mode and PWM Control mode for RGB lighting effects. The maximum output current can be adjusted in 8 levels (5mA~40mA). In PWM Control mode, the PWM duty cycle of each output can be independently programmed and controlled in 256 steps to simplify color mixing. In One Shot Programming mode, the timing characteristics for output current - current rising, holding, falling and off time, can be adjusted individually so that each output can independently maintain a pre-established pattern achieving mixing color breathing or a single color breathing without requiring any additional interface activity, thus saving valuable system resources. The IS31FL3199 includes an audio modulated display mode, wherein the brightness of LED can be modulated by audio signal. There is a cascade pin for the synchronization of two chips. IS31FL3199 is available in QFN-20 (3mm × 3mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
