CXLE81106增压转换器包含一个0.46Ω的内部开关。该集成电路工作在恒定频率600千赫，允许使用微型，低成本和低高度的电感和电容器。集成电路的工作电压为2.7伏至7伏。采用大补偿电容器消除启动时的大涌流。恒定频率电流模式的PWM结构导致低，可预测的输出噪声。该CXL8106包括按周期700毫安电流限制，以最大限度地提高电感电流和过温保护电路。当VOUT超过38V时，将启用过电压保护。LED的电流由FB和GND之间连接的电阻器设置。
2.7V至7V输入电压范围
·600kHz工作频率
·38V高输出电压
·过电压保护
5kHz至100kHz的脉宽调制亮度控制
内置循环电流限制
·0.2V低参考电压
