請教!這句是什么意思?

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.

有一個更繞嘴: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?

控制環(huán)有一個窄頻寬使得它對出現(xiàn)在輸出端的雙倍工頻的紋波不甚敏感.

就這樣? 還是open loop crossover frequency (開環(huán)交叉/交越頻率)?

請教: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是什么東東,明文是“金屬制的軌跡”應該不是這個意思.
