IS31FL3197 CHARGE PUMP RGBW LED DRIVER WITH PROGRAMMABLE SELF-RUNNING PATTERNS May 2022 GENERAL DESCRIPTION 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 the battery’s state of charge. This DC/DC converter operates at a high switching frequency which enables the use of small external capacitors and achieves a 90% peak efficiency. To conserve battery life, the charge pump goes into high impedance mode whenever the IS31FL3197 is shutdown.
