ISL95808HRZ-T具有4A的典型灌電流，用于下柵極驅動器。該電流能夠保持較低的MOSFET在相位節點的上升沿關閉。這個防止由于高dv / dt而引起的直通功率損耗相電壓。工作電壓匹配30V移動電話中常用的MOSFET的擊穿電壓電腦電源。
ISL95808HRZ-T還具有三態PWM輸入。這個PWM輸入，與Intersil的多相PWM一起使用控制器，將防止在CPU期間輸出負電壓關掉。此功能消除了保護性的肖特基二極管通常在微處理器電源系統中看到。MOSFET柵極可使用以下器件有效切換到2MHz
ISL95808HRZ-T。每個驅動器均能夠驅動3000pF負載傳播延遲為8ns，轉換時間低于10ns。自舉是通過內部肖特基實現的二極管。這樣可以降低系統成本和復雜性，同時允許適用于高性能MOSFET。適應性強集成了射擊保護MOSFET同時導通。
ISL95808HRZ-T中集成了一個二極管仿真功能，以在輕負載條件下提高轉換器效率。這個該功能還允許單調啟動為預偏置輸出。啟用二極管仿真后，驅動程序將允許通過檢測何時不連續傳導模式電感電流達到零，然后關閉低端MOSFET柵極。
ISL95808HRZ-T還具有非常低的關斷電源電流（5V，3μA）以確保低功耗。
