General Description

The AT731 is a step-up DC/DC converter specifically designed to drive white LEDs with a constant current.

The device can drive two, three or four LEDs in series from a Li-lon cell.

Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

Key Features
