AAT3129 | High Efficiency 1X/1.5X/2X Charge Pump For RGB Color LED

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 Low external parts count (two 1F flying capacitors and two small bypass capacitors at VIN and OUT) makes the AAT3129 ideally suited for small battery-powered applications. The AAT3129 has a Thermal Management system to protect the device in the event of a short-circuit 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 1A. The AAT3129 is available in a 12-pin TSOPJW package.
