R7779 是一款高性能、電流模式、有高壓啟動元件整合在內的 PWM 控制器。在啟動過程中,為能有快速啟動,電流源通過整合的高壓元件對 VDD 電容器充電,而它在一般正常操作時是不會消耗功率的。R7779 提供用戶一個優異的、有更高效率、少量外部元件、低成本解決方案的 AC/DC 電源應用。在微小型 SOP-8 封裝之下,它還具有頻率抖動,欠壓鎖定 (UVLO),前緣遮蔽 (LEB),內部斜率補償等特點。它提供了過溫保護 (OTP),過負載保護 (OLP),和過壓保護 (OVP) 等完整的保護。此外,它也提供了當轉換器處於睡眠模式時,零功率應用的一種特殊介面。 EN/DIS 接腳從次級純量控制器接收 ON/OFF 信號。在電源關閉時,控制器可完全關閉,只需相當低的功耗。
