最近還是翻譯電源管理芯片SC1404的內(nèi)容.感覺專業(yè)英語真的好難翻譯.很多時候語不達(dá)意.
希望高手不吝賜教,謝謝
雖然說翻譯出來了,但是別扭的很,而且沒有表達(dá)出應(yīng)有的意思出來.到現(xiàn)在,我也沒真正搞清楚這段英語的意思.
原文:
Gate Drive / Control
The gate drivers on the SC1404 are designed to switch large mosfets. The high-side gate driver must drive the gate of high-side mosfet above the V+ input. The supply for the gate drivers is generated by charging a boostrap capacitor from the VL supply when the low-side driver is on. In continuous conduction mode, the low-side driver output that controls the synchronous rectifier in the power stage is on when the high-side driver is off. Under light
load conditions when PSAVE# pin is low, the inductor ripple current will approach the point where it reverses polarity. This is detected by the low-side driver control and the synchronous rectifier is turned off before the current reverses, preventing energy drain from the output. The low-side driver operation is also affected by various fault conditions as described in the Fault Protection section.
我的翻譯:
SC1404的門驅(qū)動設(shè)計于開關(guān)大功率場效應(yīng)管.高邊門驅(qū)動必須能夠驅(qū)動電壓輸入超過V+的高邊MOSFET.門驅(qū)動電壓由VL對升壓電容充電產(chǎn)生,充電發(fā)生在低邊驅(qū)動開啟時候.在持續(xù)傳導(dǎo)模式,當(dāng)高邊驅(qū)動關(guān)閉時,低邊驅(qū)動輸出打開.低邊驅(qū)動控制電源的同步校正.在輕負(fù)載條件下,PSAVE#管腳處于低電平,感應(yīng)紋波電流將逼近于反極性的那個點.這被低邊驅(qū)動檢測到,在電流反向之前,同步校正器將被關(guān)閉,避免能量浪費.低邊驅(qū)動也受出錯保護(hù)部分描述的各種出錯情況影響.
