描述：ISL62771HRTZ-T
ISL62771HRTZ-T完全符合 AMD Fusion SVI 2.0 和為微處理器和圖形提供完整的解決方案處理器核心功率。ISL62771HRTZ-T控制器支持兩個具有三個集成柵極驅動器的穩壓器 (VR)。這Core VR 支持 2 相或 1 相配置，而北橋 VR 支持一相操作。兩個 VR 共享一個串行控制總線與 AMD CPU 通信并實現與兩芯片相比，成本更低，電路板面積更小解決方案。PWM 調制器基于 Intersil 的魯棒紋波調節器 R3™ 技術。與傳統調制器相比，R3 調制器可以自動改變開關頻率在負載瞬變期間獲得更快的瞬態穩定時間和提高輕載效率。
ISL62771HRTZ-T具有其他幾個關鍵特性。兩個輸出支持帶有單個 NTC 熱敏電阻的 DCR 電流感應，用于DCR 溫度補償或精確的電阻電流感應。兩個輸出都利用遠程電壓感應，可調開關頻率、OC 保護和電源良好。
