太大了不能穿diode ever operate DCM, No, this converter cannot operate in DCM because the ,synchronous rectifier ,is a ,two- quadrant current-bi-directional switch, , Thus, a change in current direction, positive or negative, will not turn the MOSFET off, DCM occurs when the switches are unipolar BUT V or I is bipolar, This always occurs when the output is unloaded for all converters。

就当五块钱喂狗了吧,我想说一下这间店有多么垃圾,双十一那天手滑拍了两件,拍错了一件,第一时间和客服说,客服告诉我退款就可以了,不会帮您发错拍件,可是结果呢,还是给我发了,发了也就算了,反正五块钱的东西,今天我收到货一看,我的天,就一件,还是那件我拍错的,我需要的那件漏发了,问客服,客服就跟我说让我退款,可是我想要的是补发不是退款,难道就因为双十一我买的价格便宜就不给我补发,什么鬼逻辑,然后我问错发的那件怎么办,他没回我,我说可以换货吗,他居然跟我说邮费自理,自理个鬼呀,明明是你们发错货了好嘛,还漏发了我需要的那一件,五块钱的衣服让我花二十的运费,搞笑呢。
