cription The AAT3129 is a high efficiency charge pump DC/DC converter with tri-mode load switch (1X) fractional (1.5X) and doubling (2X) conversion for color LED applications. A single current source output provides a regulated current to drive R, G, and B LEDs via three internal switches. With a simple single wire serial bus, the RGB module can be easily controlled to display 4096 colors. Skyworks' Advanced Simple Serial Control (AS2Cwire™) serial digital input is used to enable, disable, and set the duty cycle of each internal MOSFET switch.
