电子类英文求翻译
Synchronous rectification reduces conduction losses in
the rectifier by shunting the normal Schottky catch diode
with a low-resistance MOSFET switch. Also, the synchronous
rectifier ensures proper start-up of the boost gatedriver
circuit. If the synchronous power MOSFETs are
omitted for cost or other reasons, replace them with a
small-signal MOSFET, such as a 2N7002.
If the circuit is operating in continuous-conduction
mode, the DL drive waveform is simply the complement
of the DH high-side drive waveform (with controlled
dead time to prevent cross-conduction or “shootthrough”).
In discontinuous (light-load) mode, the synchronous
switch is turned off as the inductor current
falls through zero. The synchronous rectifier works
under all operating conditions, including Idle Mode.
The SECFB signal further controls the synchronous
switch timing in order to improve multiple-output crossregulation
(see Secondary Feedback Regulation Loop
section).

同步整流通过并联普通的肖特基钳位二极管和低电阻的MOSFET开关来减少整流器里的导电消耗.而且,这个同步的整流器保证了升压gatedriver电路的正常启动.如果因为花费或者其他原因这些同步功率MOSFET被省去,用一个小信号的MOSFET来替代它们,比如一个2N7002.如果电路在持续通电的模式下,DL驱动器波形就是DH高压侧驱动器波形补充 (带有控制的死区时间来防止交叉导通或者直通问题).在不持续通电模式下(轻负荷),这个同步开关是关闭的是因为电感电流掉到了0.这个同步整流器可以在任何工作环境下运行,包括空闲模式.二级反馈信号能进一步控制同步开关的时间,这样才能加强多路输出里的交叉调节.(见二级反馈调节环路部分)
亲,翻译不易,好多东西我还没学呢,有一些没翻译的简写和专有名词...
