AAT3129 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.
AAT3129 Key Features
- ChargePump™
- condition on any of the output pins. Built-in soft- start circuitry prevents excessive inrush current
- during start-up. High switching frequency enables
- the use of small external capacitors. A low current
- shutdown feature disconnects the load from VIN
- and reduces quiescent current to less than 1μA
- The AAT3129 is available in a Pb-free, 12-pin
- TSOPJW package
