【产品】离线式恒流/恒压PSR控制器TC2525GA/B,空载功耗小于75mW@230V
富满电子推出的TC2525GA/TC2525GB是一种高性能的用于电池充电器和适配器的电源控制器,内置功率三极管。该芯片采用脉冲频率调制(PFM)的方法来建立断续导通模式(DCM)反激式电源。
TC2525GA/TC2525GB提供精确的恒定电压,恒定电流(CV / CC)不需要光耦合器和二次控制电路调节。消除了环路补偿电路的需要,同时保持良好的稳定性。TC2525GA/TC2525GB可以实现良好的线性调整率和负载调整率,以及较高的平均效率,满足空载功耗小于75mW@230V。
TC2525GA/TC2525GB有一个专有的输出电缆压降补偿功能,即输出线损补偿,线损补偿值可调整,能有效补偿在输出线上的损耗压降。
TC2525GA/B离线式恒流/恒压PSR控制器的特点
原边反馈控制,高精度恒流、恒压
小于75mW@230V待机功耗
内置线损补偿
恒流变化下,可调直流线损补偿
随机频率抖动调制减少系统电磁干扰
