【选型】新电元PFC+LLC控制芯片MCZ5209选用于200W电源项目,可实现高压启动,能同时集成PFC+LLC
开关电源超过一定的功率时,为了减小电源谐波对输入电网的影响,需要加入功率因数校正电路(PFC)。同时为了提高电源效率,后级AC-DC部分会采用LLC方案。传统方案会采用分立PFC+LLC方案。本文推荐的SHINDENGEN(新电元)集成PFC+LLC方案可以大大简化设计,同时带来电源效率的显著提升。
图1 分立PFC+LLC与集成方案对比
高功率电源设计的控制芯片需要满足哪些要求,才能使设计更简单、效率更高?
(1)控制芯片最好能同时集成PFC+LLC,这样不需要使用单独控制IC或者使用分立方案,整体设计起来会更方便。选取好的PFC工作模式,会带来高效率以及低噪声的好处;
(2)最好控制芯片能够实现高压启动功能,这样不需要外置高压启动电路,同时最好能实现半桥LLC电路中高边MOSFET直接驱动。
新电元的PFC+LLC控制芯片MCZ5209满足设计要求:
(1)MCZ5209高度集成PFC+LLC,同时PFC控制模式采用临界电流控制模式,轻松实现高效率以及低噪声。
临界电流模式具有谷底导通以及零反向恢复电流的优势,这样会带来效率的大大提升,同时该模式需要采用电感电流,可以实现对开关电流的限制来增强电源的系统安全功能。
(2)MCZ5209可以实现高压启动,无需外置启动电阻,大大简化设计。同时可以实现LLC高边驱动,只需要外置自举二极管以及自举电容。
图2 MCZ5209高压自启动以及LLC高边驱动电路
综上所述,MCZ5209非常合适用于功率超过200W的电源应用,集成度高,设计简单。临界电流模式带来的效率的提升,可以显著提高电源产品性能。
