AAT3113 | High Efficiency 1.5x Fractional Charge Pump For White LED Applications

The AAT3113 4 are low noise, constant frequency Charge Pump DC/DC converters that use fractional (1.5X) conversion to increase efficiency in white LED applications. The devices CAN be used to produce current levels up to 20mA for each output from a 2.7V to 5.5V input. Low external parts counts (two 1F flying capacitors and two small bypass capacitors at VIN and OUT) make the AAT3113 4 ideally suited for small battery-power applications. AnalogicTechs Simple Serial Control (S2Cwire) Interface is used to enable, disable, and set the LED drive current for a 32-level logarithmic scale LED brightness control. The AAT3113 4 have 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 AAT3113 provides four LED current source outputs, and the AAT3114 provides six. The AAT3113 4 are available in 16-pin quad QFN packages; the AAT3113 is also available in a 12-pin TSOPJW package
