The IS31FL3729 is a general purpose 16×8 or 15×9 matrix LED driver programmed via a 1MHz I2C bus compatible interface. Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC current scaling for color calibration. The combination enables 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustment for each CS.
a very low shutdown and quiescent (operational) current. It also supports selectable noise reduction features such as PWM clock spread spectrum and 180 degree phase shifting.
IS31FL3729 is available in QFN-32 (4mm×4mm) and eTQFP-32 packages. It operates from 2.7V to 5.5V over the full temperature range of -40°C to +125°C.
