IS31FL3193-DLS2-TR

IS31FL3193 is a 3-channel fun LED driver which features two-dimensional auto breathing mode. It has One Shot Programming mode and PWM Control mode for RGB lighting effects. The maximum output current can be adjusted in 5 levels (5mA~42mA). 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. IS31FL3193 is available in DFN-10 (3mm×3mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
