近年来,随着USB PD快充的应用越来越广泛,大功率的PD快充,在笔记本上一定程度的取代了传统圆口的电源,让笔记本的使用更加灵活。同时PD快充也应用在手机的快速充电上,在半小时之内充满电,这在过去都是不可想象的。
针对高功率密度电源的需求,必易微高达500kHz的单管反激氮化镓驱动控制器。而大功率的PD快充和大功率电源,都离不开PFC芯片。在充电器内部加入PFC芯片,可以通过升压的方式来减小充电器初级电容容量,缩小充电器体积,另外通过功率因数校正,可以消除大容量电解电容充电时的冲击电流,避免充电器工作对电网造成干扰。
致力于电源管理方案的必易微电子,推出了一款临界模式的升压PFC控制器KP2801,在支持单绕组电感低成本设计的同时还可以获得优秀的谐波和效率表现。
图 1
必易微KP2801内置650V高压启动电路,启动时间小于0.2秒,当后级搭配LLC时保证了电源启动过程中更早建立稳定的母线电压;KP2801针对轻载效率和待机损耗进行优化,可实现0.95以上的高PF值以及低于8%的总谐波电流失真,并针对轻载的总谐波电流失真进行优化。
KP2801系列是高度集成的恒压Boost控制器,芯片采用了工作在临界导通模式下的升压功率因素控制(BCM Boost-PFC),高PF值,低THD。
KP2801内部集成消磁信号检测技术和高压供电电路,无需辅助绕组检测消磁和供电,简化了系统的设计和生产成本。
KP2801集成有完备的保护能以系统安全可靠地运行,如:VDD欠压功能(UVLO)、交流输入欠压保护(BOP),输出过压保护(UOP),输出欠压保护(UVP)、过热保护(OTP)、逐周期电流限制(OCP),异常过流保护(AOCP)以及管脚开短路保护。
