描述：ISL8121IRZ-T
ISL8121IRZ-T 是一款兩相降壓 PWM 控制器具有 3V 至 20V 的輸入電壓范圍和集成 MOSFET 驅(qū)動(dòng)器。精密電壓為負(fù)載點(diǎn)和其他需要高效和緊湊的大電流應(yīng)用提供調(diào)節(jié)執(zhí)行。多相降壓轉(zhuǎn)換器架構(gòu)使用交錯(cuò)時(shí)序進(jìn)行乘法通道紋波頻率允許更小的濾波器電感器并降低輸入和輸出紋波電流由于紋波抵消效應(yīng)。更低的紋波導(dǎo)致更少的輸入和輸出電容器。較小并且可以使用低成本晶體管更高的效率和更低的功耗。
ISL8121IRZ-T 提供內(nèi)部 0.6V 參考電壓系統(tǒng)調(diào)節(jié)精度±0.8%（工業(yè)溫度范圍），可選外部參考輸入和用戶可調(diào)節(jié)的開關(guān)頻率。統(tǒng)一針對(duì)遠(yuǎn)程電壓的增益差分放大器能力增強(qiáng)了調(diào)節(jié)。一種力量輸出電壓為好信號(hào) (PGD) 時(shí)發(fā)出規(guī)定的窗口內(nèi)。內(nèi)部分流器具在有可選外部連接功能的調(diào)節(jié)器擴(kuò)展了操作輸入電壓范圍。為了需要電壓跟蹤或排序的應(yīng)用，
ISL8121IRZ-T 提供了許多可能性，包括巧合、比率或偏移跟蹤，以及順序啟動(dòng)，用戶可在很寬的范圍內(nèi)進(jìn)行調(diào)整的應(yīng)用程序。附加功能包括過壓和過流保護(hù)。過流保護(hù)可以為各種應(yīng)用量身定制，無(wú)需附加部分。 ISL8121IRZ-T 使用成本和節(jié)省空間的 rDS(ON) 感測(cè)來(lái)實(shí)現(xiàn)通道電流平衡，動(dòng)態(tài)電壓定位和過流保護(hù)。通道電流平衡是自動(dòng)的精確的集成電流平衡控制系統(tǒng)。
