电源管理IC

介绍\n 这款高度集成的原边反馈控制芯片包含了许多功能，这些功能有效地提高了小功率反激变换器性能。原边反馈的拓扑简化了电路的设计，无需副边反馈，就可以实现精确的恒压和恒流。通过芯片内部的抖频技术，EMI 可以使用最小的滤波器来解决。所以，与传统的设计和线性变压器比较，充电器更小更轻了。\n 这款原边反馈控制芯片工作在脉冲频率调制（PFM）模式下，负载越轻，频率越小，所以轻载时系统的功耗很小。启动电流最大为10uA，所以可以使用很大的启动电阻从而提高了节能效果。\n 这款原边控制芯片同时也提供了非常多的保护功能。FB 引脚配置了过压保护和输入欠压锁定。每一周期的电流限制和恒流控 ：\n\n原边反馈的恒压(CV)和恒流(CC)控制\n3%的恒压精度，2%的恒流精度\n节能模式：脉冲频率调制控制模式(PFM)\n内置700 功率管\n内置抖频来降低EMI\n逐周期的电流限制\n内置软启动\n低启动电流(5uA)\n过压保护(OVP)\n欠压锁定(UVLO)\n过温保护(OTP)\n输出短路保护\n前沿消隐(LEB)\n可调节输出线补偿电压\n无光耦及TL431 反馈;
