AAT3114A - High Efficiency 1.5X Fractional Charge Pumps

Download the AAT3114A datasheet PDF (AAT3114 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for high efficiency 1.5x fractional charge pumps.

Description

The AAT3113 and AAT3114/14A 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.

Features

  • AnalogicTech’s Simple Serial Control™ (S2Cwire™) interface is used to enable, disable, and set the LED drive current for 32-level logarithmic scale LED brightness control. AAT3113 and AAT3114/14A devices have a thermal management system for protection in the event of a short-circuit condition on any of the output pins. Built-in.

High Efficiency 1.5X Fractional Charge Pumps For White LED Applications General Description The AAT3113 and AAT3114/14A 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.
