产品概述 返回TOP3tQ嘉泰姆
The CXLE8122 is a step-up DC/DC converter specifically designed to drive up to 5 series white3tQ嘉泰姆
LEDs with constant current. Series connection of the LEDs provides identical LED currents3tQ嘉泰姆
resulting in uniform brightness and eliminates the need for ballast resistors. The CXLE81223tQ嘉泰姆
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.3tQ嘉泰姆
The CXLE8122 is available in low profile SOT-23-6 package. 3tQ嘉泰姆
