RRW21111 是一款系统级封装(SiP)产品,集成了 700V SuperGaN® FET 与高性能数字式 AC/DC 初级侧调节(PSR)反激式控制器。 其可配置的轻载模式允许设计人员仅通过一个外部电阻,即可针对超低空载功耗或快速瞬态响应进行参数调优。 该器件工作于准谐振模式,不仅能在重载条件下实现高效率,还能减少外部元件数量、简化 EMI 设计,并降低整体物料清单成本。
PrimAccurate™ 初级侧调节技术消除了对次级侧反馈元件的需求,同时仍能保持出色的线性调整率与负载调整率。 其数字控制架构省去了外部环路补偿需求,并通过逐脉冲波形分析实现了比传统解决方案更快的动态响应速度。 内置功率限制功能支持在宽范围离线输入电压下对变压器进行优化设计;RRW21111 通常适用于功率约为 65W 的应用场景。
该器件实现了较高的平均有源效率,且空载功耗低于 75mW。 其软启动功能确保了在任意输出电压下对大容量容性负载实现平滑启动,因此非常适用于网络设备和显示器适配器应用。
RRW21111 集成了内部和外部过压保护功能,其中外部保护通路提供了辅助输出过压保护,提升了系统鲁棒性。
