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.PDV嘉泰姆

Series connection of the LEDs provides identical LED current resulting in uniform brightness andPDV嘉泰姆

eliminating the need for ballast resistors. The CXAC85183 switches at 1MHz, allowing the use of anyPDV嘉泰姆

tiny external components. The output capacitor can be as small as 1μF, saving space and costPDV嘉泰姆

versus alternative solutions. A low 95mV feedback voltage minimizes power loss in the current setting resistor for better efficiency.PDV嘉泰姆

CXAC85183 is available in low profile SOT-23-5L package.PDV嘉泰姆
