IS31FL3197 CHARGE PUMP RGBW LED DRIVER

The IS31FL3197 is a charge pump LED driver with programmable sequence operation for automated RGBW lighting effects. It is capable of driving 4 LEDs up to 10mA (adjustable in 256 current levels and 4096 PWM levels) from a small coin size battery supply. The built−in charge pump structure will automatically toggle between 1x, 1.5x or 2x operation depending on.

Features

• 2.0V to 3.3V supply voltage
• Charge pump - 1x, 1.5x, 2x operating modes - Highly efficient across battery state of charge - 1MHz constant frequency
• Power saving operating - Quiescent operating current 700µA (Typ.) - Shutdown current 1µA (Typ.)
• Support four LEDs - RGBW - Resistor sets maximum 10mA output current per LED - Each LED has 8-bit programmable current levels - Each LED has 12-bit programmable PWM levels
• LEDs operate with pre-established patterns - Once programmed runs without micro - OUT1~OUT3 have their own fade ON/OFF timing registers (TS~T4) with independent start/ stop/cr.
