请教!这句是什么意思?

The former works in TM (Transition Mode, i.e. on the boundary between continuous and discontinuous inductor current mode), therefore at a frequency depending on both input voltage and output current. The latter works at a fixed frequency, imposed by the synchronisation signal, and is therefore
completely equivalent to a flyback converter
based on a standard PWM controller.

有一个更绕嘴:the control loop has a narrow bandwidth so as to be little sensitive to the twice mains frequency ripple appearing at the output.什么意思啊?

控制环有一个窄频宽使得它对出现在输出端的双倍工频的纹波不甚敏感.

就这样? 还是open loop crossover frequency (开环交叉/交越频率)?

有点意思,与能量有边,老外的脑子也象进水,有话就是不会好好说!

除了为得到一个窄的整体频宽而使事情复杂化之外…
...这参数的统计散布量

请教:a small filter capacitor is placed close to the VCOMP pin of the control IC to attenuate high frequency switching noise being picked up by the metal trace from the opto-coupler to the control IC. 中的metal trace是什么东东,明文是“金属制的轨迹”应该不是这个意思.
