目录7.相关产品 产品概述 返回TOP The CXSU63168 is a step‐up DC/DC converter designed for driving up to 5 white LEDs in series from a single cell Lithium Ion battery with constant current. Because it directly regulates output current, the CXSU63168 is ideal for driving light emitting diodes (LEDs) whose light intensity is proportional to the current passing through them, not the voltage across their terminals. A single external resistor sets LED current between 2mA and 20mA, which can then be easily adjusted using either a DC voltage or a pulse width modulated (PWM) signal up to 100KHz. Its low 104mV feedback voltage reduces power loss and improves efficiency. The OV pin monitors the output voltage and turns off the converter if an over‐voltage condition is present due to an open circuit condition. The CXSU63168 is available in SOT23‐6 packages.产品特点 返回TOP z Drives Up to 5 Series White LEDs from 3V z Up to 87% Efficiency z 1.25MHz Fixed Switching Frequency z Low 104mV Feedback Voltage z Open Load Shutdown z PWM Dimming z SOT23‐6 Packages z RoHS compliant 应用范围 返回TOP z Cell Phones z Handheld Computers and PDAs z Digital Cameras z Small LCD Displays 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 产品封装图 返回TOP
