Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminates the need for ballast resistors. The CXLE8122 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 CXLE8122 is available in low profile SOT-23-6 package. 产品特点 返回TOP Inherently Matched LED Current High Efficiency:82% Drives Up to Five LEDs from 2.2V Supply 17V Over Voltage Protection Fast 1.4MHz Switching Frequency Requires Only 1μF Output Capacitors SOT-23-6 Packag 应用范围 返回TOP
