The CXAC85183 is a step-up DC/DC converter specifically designed to drive white LEDs with a
constant current. The device can drive two, three,four, or five LEDs in series from a Li-Ion cell.
Series connection of the LEDs provides identical LED current resulting in uniform brightness and
eliminating the need for ballast resistors. The CXAC85183 switches at 1MHz, allowing the use of any
tiny external components. The output capacitor can be as small as 1μF, saving space and cost
versus alternative solutions. A low 95mV feedback voltage minimizes power loss in the current setting
resistor for better efficiency.
