描述

RRW22125 是一款系统级封装（SiP）产品，集成了 700V SuperGaN® FET 与高性能 AC/DC 初级侧数字反激式控制器，适配次级侧调节（SSR）架构。 该器件专为 25W 至 45W 适配器设计，支持配合 TL431 分流稳压器及其他第三方次级侧控制器工作，适用于广泛的终端应用领域。

该器件工作于恒频准谐振（QR）模式，并采用自适应多模式控制（MMC）技术，涵盖脉宽调制（PWM）、脉冲频率调制（PFM）以及突发模式（Burst Mode）等多种工作模式。 这种控制架构能够在各种负载条件下有效提升效率、降低电磁干扰（EMI），并消除音频噪声。

搭配 TL431 或其他次级侧控制器使用时，RRW22125 在典型大功率设计中能够实现精准恒压（CV）、快速动态负载响应，并将待机功耗控制在 75mW 以下。 其集成的保护功能以及对双极性辅助绕组检测的支持，不仅简化了变压器设计，提升了 EMI 性能，还有助于降低整体系统成本。
