AAT3132 Datasheet High Efficiency 1.5X Fractional Charge Pump

Manufacturer: Skyworks Solutions

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.
