描述:ISL6341CRZ-T
ISL6341、ISL6341A、ISL6341B、ISL6341CRZ-T實施完全控制的簡單工作和DC/DC降壓轉換器驅動保護方案同步降壓拓撲中的 N 溝道 MOSFET。自從它可以使用 5V 或 12V 電源,這一系列IC 可用于多種應用中系統。它集成了控制、柵極驅動器、輸出調整、監控和保護功能于一體10 Ld 薄型 DFN 封裝。
ISL6341、ISL6341A、ISL6341B、ISL6341CRZ-T(以下簡稱稱為“ISL6341x”,除非需要)提供單反饋回路,具有快速瞬態的電壓模式控制回復。輸出電壓可以精確調節為低至 0.8V,最大容差為 ±0.8%過溫和線電壓變化。固定頻率振蕩器和寬占空比范圍降低了設計復雜性,同時平衡典型的應用成本和效率。這頻率、占空比和 OCP 響應是唯一的
ISL6341CRZ-T 版本之間的差異。見表 1。過流保護是由監控下 MOSFET 的 rDS(ON) 以抑制 PWM正確操作(參見“過流保護 (OCP)”有關詳細信息,請參見第 8 頁)。這種方法簡化了實施并通過消除需要一個電流檢測電阻。輸出電壓也是監測欠壓和過壓保護,在除了監視 PGOOD 輸出。
