带 CC/CV 控制和 700V MOSFET 离线原边调节器

MP020A-5 是一款离线原边调节器,可提供精确的恒定电压和恒定电流控制,无需光电耦合器或副边反馈电路。MP020A-5 集成了 700V MOSFET。

MP020A-5 采用可变关断时间控制方式,让反激转换器工作在断续导通模式(DCM)。MP020A-5 还具有多种保护功能,如 VCC 欠压锁定保护(UVLO)、过流保护(OCP)、过温保护(OTP)、开路保护(OCkP)和过压保护(OVP)。其内部高压启动电流源和节电技术可将空载功率损耗限制在30mW 以内。

MP020A-5 的可变开关频率技术能实现自然抖频效果并降低 EMI,非常适用于离线、低功率电池充电器和适配器。
