AAT3132A - High Efficiency 1.5X Fractional Charge Pump

Download the AAT3132A datasheet PDF. This datasheet also covers the AAT3132 variant, as both devices belong to the same high efficiency 1.5x fractional charge pump family and are provided as variant models within a single manufacturer datasheet.

Description

The AAT3132/32A is a low noise, constant frequency charge pump DC/DC converter that uses fractional (1.5X) conversion to maximize efficiency for white LED applications.

Features

  • ChargePump™ AnalogicTech's Simple Serial Control™ (S2Cwire™) interface is used to enable, disable, and set the LED drive current in two groups: the three 20mA outputs and the single 30mA output with multiple level logarithmic scales. The AAT3132/32A has a thermal management system to protect the device in the event of a short-circuit co.

AAT3132/32A High Efficiency 1.5X Fractional Charge Pump for White LED Applications General Description The AAT3132/32A is a low noise, constant frequency charge pump DC/DC converter that uses fractional (1.5X) conversion to maximize efficiency for white LED applications. The device can be used to produce current levels up to 20mA in three of its outputs and up to 25 or 30mA in one of its outputs to drive LEDs from a 2.7V to 5.5V input. Outputs may be operated individually or paralleled for driving higher-current LEDs. A low external parts count (two 1µF flying capacitors and two small 1µF capacitors at VIN and OUT) makes the AAT3132/32A ideally suited for small battery-powered applications.
