The CXSU63227 CXSU63228 is a step-up DC/DC converter specifically designed to drive up to 6 series white LEDs with constant current. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. The CXSU63227 CXSU63228 switches at 1.4MHz, allowing the use of tiny external components. A low 0.25V feedback voltage minimizes power loss in the current setting resistor for high efficiency. The OVP pin monitors the output voltage and turns off the converter whenever the LEDs are open. The CXSU63227 CXSU63228 is available in low profile SOT-23-6 package.
