IS31FL3298 CHARGE PUMP RGB LED DRIVER WITH PROGRAMMABLE SELF-RUNNING PATTERNS May 2024 GENERAL DESCRIPTION The IS31FL3298 is a charge pump LED driver with programmable sequence operation for automated RGBW lighting effects. It is capable of driving 9 LEDs up to 20mA (adjustable in 256 current levels and 4096 PWM levels) from battery power supply. The built−in charge pump structure will automatically toggle between 1x, or 1.5x 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 IS31FL3298 is shutdown.
