High Efficiency 1X/1.
5X/2X Charge Pump for RGB Color LED Applications General Description
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.
AnalogicTech's Advanced Simple Serial Control™ (AS2Cwire™) serial digital input is used to enable, disable, and set the duty cycle of each internal
MOSFET switch.
