RT9605B 為高頻、三通道同步降壓 MOSFET 驅動器,特別設計於驅動六個 N-MOSFET 的應用。此產品可和立錡應用于高密度電源的多相 PWM 降壓控制器家族搭配。RT9605B 的輸出驅動器可以有效的操作在 300kHz 頻率。操作在高頻時,必須非常注意散熱問題。RT9605B 的每一個驅動器能在 30/40ns 上升/下降時間內驅動 3nF 負載。此 IC 於上橋僅用了一個外部電容和一個二極體,這減少了電路的複雜性,並可使用效能更好、性價比高的 N-MOSFET。所有的驅動器都具有適性擊穿保護。RT9605B 會在剛啟動時且多相 PWM 控制器控制前,偵測故障狀況。因此,輸入會被鎖定在關閉狀態。RT9605B 提供 WQFN-24L 4x4 封裝。
