CXLE8606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。设备可以驱动一个锂离子电池最多可串联8个LED。LED电流由外部电阻（RSET）设置并直接调节
通过外部电阻RSET的反馈（FB）电压（典型值：200mV）。为了确保操作过程中的最大安全性，输出集成了过电压保护，以防止损坏。在某些故障情况下的装置。OVP电压可由两个外部电阻编程。

产品概述 返回TOP
The CXLE8606 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 CXLE8606 is available in a tiny SOP8/PP package.
