Product details

Description

The AAT3194 is a 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

ChargePump™ VIN Range: 2.7V to 5.5V 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.
