RT9624K/RT9624L 是一款高頻率、同步整流單相 MOSFET 驅動器,專為一般 MOSFET 驅動應用及高效能 CPU 電壓調節器(VR)應用而設計。 RT9624K/RT9624L 的供電電壓範圍為 4.5V 至 13.2V,適用的功率級輸入電壓(VIN)範圍為 5V 至 24V。此外,產品內建電源開關,可取代外部自舉二極體(Bootstrap Diode),簡化電路設計。 RT9624K/RT9624L 可有效支援高達 500kHz 的開關頻率。產品同時具備高側閘極(UGATE)與低側閘極(LGATE)驅動電路,適用於同步整流 DC/DC 轉換器應用。內建防直通保護(Shoot-Through Protection)機制,可避免高側與低側功率 MOSFET 同時導通而造成短路。 RT9624K/RT9624L 提供三態 PWM 輸入關閉功能及 EN 腳位關閉功能,當啟用關閉模式時,可強制 UGATE 與 LGATE 輸出維持低電位。 RT9624K 採用小尺寸 WDFN-8SL(2mm × 2mm)封裝;RT9624L 採用 WDFN-8L(3mm × 3mm)封裝。 建議接面溫度範圍為 -40°C 至 125°C,環境溫度範圍為 -40°C 至 85°C。
