描述:ISL8014AIRZ-T
ISL8014AIRZ-T 是一種高效率、單片、同步可提供高達 4A 的降壓 DC/DC 轉換器2.8V 至 5.5V 輸入電源的連續輸出電流。它使用電流控制架構來提供非常低的負載具有快速瞬態響應的高頻循環操作和出色的環路穩定性。
ISL8014AIRZ-T 集成了一對低導通電阻 P 溝道和 N 溝道內部 MOSFET 以最大限度地提高效率和盡量減少外部元件數量。 100% 占空比操作允許在 4A 時低于 400mV 的壓差輸出電流。高 1MHz 脈寬調制 (PWM)開關頻率允許使用小的外部組件和 SYNC 輸入使多個 IC 能夠同步異相以減少紋波并消除跳動頻率。
ISL8014AIRZ-T 可配置為不連續或強制輕負載下連續運行。強制連續操作可減少噪音和射頻干擾,同時不連續模式通過減少輕載時的開關損耗。故障保護由內部打嗝模式電流提供在短路和過流情況下進行限制,輸出過壓比較器和過溫監控器電路。電源良好輸出電壓監視器指示何時輸出處于調節狀態。
ISL8014AIRZ-T 采用節省空間的 4mmx4mm QFN,帶有裸露焊盤引線框架的無鉛封裝,用于低熱阻。
ISL8014AIRZ-T 提供 1ms 電源良好 (PG) 定時器充電。關機時,ISL8014AIRZ-T 對輸出進行放電電容器。其他特性包括內部軟啟動、內部補償、過流保護和熱關斷。
ISL8014AIRZ-T 采用 16 Ld 4mmx4mm QFN 封裝最大高度為 1mm。完整的轉換器占小于 0.4in2 的面積。
