概览

FSB127H 是采用Fairchild创新型 mWSaver® 技术的新一代绿色模式Fairchild电源开关 (FPS™)，能够显著降低待机和空载功耗，从而符合所有全球待机模式效率准则。它在单封装中集成了先进的电流模式脉宽调制器(PWM)和耐雪崩的700V SenseFET器件，与先前的解决方案相比，其辅助功率设计具有更高待机能效、更小巧、更高可靠性以及更低系统成本的优势。
Fairchild的 mWSaver™ 技术可提供同类最佳的最低空载和轻载功耗。创新的Ax-CAP™法，是五种专有mWSaver™技术之一，它通过消除X电容放电电阻，同时满足IEC61010-1的安全要求，可以最大限度地减少电磁干扰(EMI)滤波阶段的损失。 mWSaver™绿色模式将会随着负载的降低而逐渐减少开关频率，从而最大限度地降低开关损耗。新的专用异步抖动功能可减少电磁干扰(EMI)辐射，并且内置的同步斜率补偿功能可在广泛的输入电压范围内进行稳定的峰值电流模式控制。专用的内部线路补偿可确保对整个通用线路电压范围进行恒定的输出功率限制。
FSB127H 只需最少的外部组件，便可为需要极低待机功耗的经济高效的反激式转换器设计提供最佳的基础平台。
