RT7752GxQ系列產品是針對USB PD和可程式控制電源應用而開發的採用准諧振模式工作的PWM控制器，可與RT7202等配合構成完整的USB PD或其他可程式控制電源系統，具有轉換效率高、符合各種安全標準的特性，在5V輸出條件下的待機消耗低於50mW。</br>RT7752GxQ針對輸出電壓範圍很寬的應用加入了一些開創性的設計，其DMAG端可通過對輸出電壓的檢測進行環路增益調節以實現系統穩定，可對輸出過壓保護閾值進行調整以確保外部元件的安全，可調整電流限制閾值以符合受限電源 (Limited Power Source, LPS) 的安全需求。</br>RT7752GxQ也同時具有眾多的保護特性如大電容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、週邊過熱保護等。在恒定輸出功率的應用中，連接在CS端的電流檢測電阻可在全輸入電壓範圍內提供精確的線路補償。</br>當次級元件如RT7202或分流調節器出現故障時，RT7752GxQ也能提供保護作用。RT7752GxQ與RT7202的結合能帶來強壯、安全的設計，可防範電源系統在與各種已知或未知的設備、電纜、插頭座等連接時可能出現的各種錯誤所帶來的安全風險。
