The AF1937 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-Ion cell.
Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.
