RT7791系列產品是針對USB PD或可程式設計電源適配器設計的PWM控制器，可與RT7202等控制器一道形成完整的電源解決方案，使最終方案具有效率高、滿足安全標準、5V輸出的待機損耗低於50mW等特性。</br>RT7791在設計上包含許多創新的理念，為寬輸出電壓的應用提供了良好的解決方案。通過DMAG引腳的使用，RT7791可以測知輸出電壓並據此調節環路增益以實現系統穩定、調節過壓保護閾值以保護週邊元件、調節電流限制閾值以滿足受限電源的安全需求。</br>RT7791系列產品均具有完備的保護性功能設計，包括輸入電容Brown-In/Brown-Out保護、VDD過壓保護、輸出過壓/欠壓保護、次級整流器短路保護和週邊元件過熱保護。為了實現恒定輸出功率調節，連接在CS引腳的電阻可在全輸入電壓範圍內被用於獲得精確的線性補償。當變壓器次級側的元件如RT7202、分流式調節器等出現失效故障時，RT7791還具有多項保護特性予以應對。</br>RT7791和RT7202結合在一起所形成的系統是穩定而又安全的，可以防範各種危險情形可能帶來的傷害，其中就包括各種常用和未知的連接形式，如與設備的連接，與不同的電纜、插頭、插座等的連接。
