CXLE8113是一种升压型DC/DC转换器，具有恒定电流，可驱动白光LED或类似产品。该设备可以从锂离子电池串联驱动多达8个LED。LED电流由外部电阻器（RSET）设置，并由外部电阻器RSET上的反馈（FB）电压（类型：200mV）直接调节。为了确保在运行期间的最大安全性，输出具有集成过电压保护，以防止在某些故障情况下对设备的损坏。OVP电压可由两个外部电阻编程。

产品概述 返回TOP
The CXLE8113 is a step-up DC/DC converter with a constant current to drive white LEDs or similar. The device can drive up to eight LEDs in series from a Li-Ion cell. The LED current is set by the external resistor (RSET) and is directly regulated by the feedback (FB) voltage (typ: 200mV) across the external resistor RSET. To ensure maximum safety during operation, the output has integrated overvoltage protection that prevents damage to the device in case of some fault conditions. The OVP voltage can be programmed by two external resistors. The CXLE8113 is available in a tiny SOP8/PP package.
