MAX8678 White LED Charge Pump with 1.1W Audio …
https://www.maximintegrated.com/en/products/power/led-drivers/MAX8678.html
The MAX8678 integrates a charge pump for white light-emitting diodes (LEDs) with an audio loudspeaker amplifier. The high-efficiency, adaptive charge pump drives up to four LEDs with constant current for uniform brightness. The LED current is adjustable from 0.1mA/LED to 24mA/LED in 31 pseudo-logarithmic steps through a single-wire serial-pulse ...
