AAT3114 - High Efficiency 1.5X Fractional Charge Pumps

Download the AAT3114 datasheet PDF. This datasheet also covers the AAT3113 variant, as both devices belong to the same high efficiency 1.5x fractional charge pumps family and are provided as variant models within a single manufacturer datasheet.

General Description

The AAT3113 and AAT3114 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.

Key Features

  • AAT3113: Four Outputs.
  • AAT3114: Six Outputs.
  • 20mA Full-Scale Current.
  • Simple Serial Control (S2Cwire) Interface.
  • 32-Position Logarithmic Scale with Digital Control.
  • Low Noise Constant Frequency Operation.
  • 33% Less Input Current Than Doubler Charge Pump.
  • High Accuracy Brightness Matching.
  • Small.

DATA SHEET AAT3113/3114 High Efficiency 1.5X Fractional Charge Pumps for White LED Applications General Description The AAT3113 and AAT3114 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. A low external parts count (two 1μF flying capacitors and two small bypass capacitors at VIN and OUT) makes these devices ideally suited for small, battery-powered applications. Skyworks' Simple Serial Control (S2Cwire™) interface is used to enable, disable, and set the LED drive current for 32-level logarithmic scale LED brightness control.
