你们飞兆半导体公司和经授权的分销商的态度太差,没有服务意识!当然你们要承担一定的后果,不替客户着想、不给客户方便,客户肯定会抛弃你!跟你们买几个样品竟然说要三周后,还说买一个包装2500PCS可以马上交货!你这不是气我吗,难道你们的东西做出来有问题,打包抛售骗钱?

首先,我不同意您的观点,对于服务来讲,除了代理商以外还有飞兆自己的FAE服务团队,我相信是您没有找对相应的接口.其次,飞兆是可以免费提供大部分产品的样品供客户开发使用的,几片是没有问题的,而且是免费的.关键是您要找对代理商,最好的方法是联系飞兆驻各地办事处.
飞兆半导体集中了大陆的FAE团队资源全面服务客户,您在本论坛提出的任何技术问题都将会得到及时全面的回复.

能在不到一个半小时做此回复,也许还有点希望!
虽然我还没有拿到FAN7530的样品,但我还是想先进一步了解它的特性,问题如下:
1、FAN7530在空载和轻载时是如何工作的,会不会有噪声?是断续的间歇工作模式还是连续的降频工作模式?有最小脉宽限制吗?
2、在FAN7530的第2Pin外加调变电流源会有什么影响,会改变它的工作频率吗?
望版主赐教,谢谢!

FAN7530 是CRM (临界导通模式)因此输入电压和负载的变化都会引起开关频率的变化,即使输入电压和负载不变,输入正弦半波的不同电压点频率也是不同的.空载或轻载时是间歇模式工作.因间歇频率很低,低于输入交流倍频,且电流很小不会有噪声问题.
2PIN加调变电流源会改变最大导通时间,因此会改变工作频率.但一般改变不很大.

在电源网上都是进行平等地交流,在探讨问题的时候不能心平气和地说吗?这位仁兄不知道你哪儿来的火气.相信你所在的公司也有客户吧,将心比心,劝你以后在公共场合改变一下说话的语气,维护好工程师队伍的形象.
哪天你若是能达到飞兆公司技术支持的水准,那就说明你进步了.
这只是作为学习电源知识的晚辈的一点见解,还请见谅.

FAN7530是CRM(临界导通模式)因此输入电压和负载的变化都会引起开关频率的变化,即使输入电压和负载不变,输入正弦半波的不同电压点频率也是不同的.空载或轻载时是间歇模式工作.因间歇频率很低,低于输入交流倍频,且电流很小不会有噪声问题.2PIN加调变电流源会改变最大导通时间,因此会改变工作频率.但一般改变不很大.

第一次与飞兆深圳办事处打交道:5月12日上午十点前与飞兆深圳办事处联系上(0755-82463088-233),咨询电源IC:FSFA2100+FAN7530,登记了公司、姓名、固定电话、手机号码,被告知会有代理商主动找来,一直到5月15日也没有任何消息,于是再与那位先生联系,他说他再和他们业务说说,现在是5月18日下午4点,飞兆公司好像还是没有主动联系的迹象,飞兆的服务一直是这样吗?
