概要:

CN3722⁽^注1)就是一款可以操作太陽升起能蓄電池用電的PWM降壓情勢充電辦理集成電路，具備太陽能電池最大功率點跟蹤功效。CN3722很(hen)是合適的對單(dan)節(jie)或(huo)多節(jie)磷(lin)酸鐵(tie)(tie)鋰(li)(li)干(gan)電池快速充(chong)電或(huo)磷(lin)酸鐵(tie)(tie)磷(lin)酸鐵(tie)(tie)鋰(li)(li)干(gan)電池快速充(chong)電的快速充(chong)電辦，享(xiang)有(you)封口形式(shi)小(xiao)，內在元(yuan)電子元(yuan)器件少和操(cao)控(kong)容易等憂點。

CN3722具備恒流和恒壓充電情勢，很是合適鋰電池或磷酸鐵鋰電池的充電。在恒壓充電情勢，恒壓充電電壓由內部電阻分壓收集設置；在恒流充電情勢，充電電流經由過程一個內部電阻設置。
