描述：ISL6545IBZ-T
ISL6545IBZ-T、ISL6545A 使工作變得簡單實施完整的控制和保護方案DC/DC 降壓轉(zhuǎn)換器驅(qū)動 N 溝道 MOSFET同步降壓拓撲。因為它可以在 5V 或12V 電源，這一款 IC 可用于多種系統(tǒng)內(nèi)的應(yīng)用程序。 ISL6545IBZ-T、ISL6545A（以下稱為“ISL6545x”，除非需要）集成了控制、柵極驅(qū)動器、輸出調(diào)節(jié)、監(jiān)控和保護功能集成到單個 8 Ld SOIC 或10 Ld DFN 封裝。
ISL6545IBZ-T 提供單反饋回路、電壓模式具有快速瞬態(tài)響應(yīng)的控制。輸出電壓可以精確調(diào)節(jié)至低至 0.6V，最大±1.0% 過溫和線電壓的容差變化。一個可選的固定頻率振蕩器（ISL6545 用于
30kHz； ISL6545A for 600kHz) 降低了設(shè)計復(fù)雜性，同時平衡典型的應(yīng)用成本和效率。誤差放大器具有 20MHz 增益帶寬產(chǎn)品和 9V/μs 壓擺率，可實現(xiàn)高轉(zhuǎn)換器帶寬以實現(xiàn)快速瞬態(tài)性能。所結(jié)果的PWM 占空比范圍從 0% 到 100%。過流保護是由監(jiān)控下 MOSFET 的 rDS(ON) 以抑制 PWM操作適當(dāng)。這種方法簡化了實施并通過消除需要一個電流檢測電阻。
