最近還是翻譯電源管理芯片SC1404的內(nèi)容.感覺(jué)專業(yè)英語(yǔ)真的好難翻譯.很多時(shí)候語(yǔ)不達(dá)意.
希望高手不吝賜教,謝謝
雖然說(shuō)翻譯出來(lái)了,但是別扭的很,而且沒(méi)有表達(dá)出應(yīng)有的意思出來(lái).到現(xiàn)在,我也沒(méi)真正搞清楚這段英語(yǔ)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.
