CXPU3360是一个高度集成的解决方案,适用于需要CV(恒压)和CC的SMPS应用(恒流)模式。它还内置了专门为独立电池充电而设计的LED驱动器应用。CXPU3360集成了三个电压基准、三个运算放大器和两个电流感应在同一集成电路中的电路。第一电压基准连同一个运算放大器控制输出电压。第二个参考电压,连同另一个运算放大器,感应并限制低压侧的电流量,因此输出端的总电流。第三电压基准和当充电电流降到编程值的10%时,运算放大器会感测到。在充电过程中,CXPU3360将打开红色LED。充电完成后,CXPU3360将点亮绿色LED。这个CXPU3360有SOP8和DIP8两种包装。

产品概述 返回TOP
CXPU3360 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC
(constant current) modes. It also has built-in LED drivers specifically designed for stand-alone Battery Charging applications. CXPU3360 integrates three voltage references, three operational amplifiers, and two current sensing circuits together in the same
IC.The 1st voltage reference,together with one operational amplifier, controls the output voltage.The 2nd voltage reference, together with another operational amplifier, senses and limits the amount of the current on the low side, hence the overall current at the output. The 3rd voltage reference and
operational amplifier senses when the charging current drops to 10% of the programmed value.During charging, CXPU3360 will turn on Red LED. When the charging is completed, CXPU3360 will turn on Green LED. The CXPU3360 is available in SOP8 and DIP8 package.
