有几个问题想请教一下.
我最近用7710点了一个13W双U型灯管和22W的环型灯管.
出现的问题是重新上电的时候 会出现7710烧毁的情况.
不知道问题出在哪里.有没有类似经验的人能指导一下
小弟万分感谢!
有人用FAN7710做个低功率的节能灯吗?

FAN7710是FSC2005年在韩国研发,2006年在中国华南地区发布,首先是找CETZGE做了首次测试,中间出现过烧机的问题,后来又经过调试,其保护功能很强大,设计的时候注意功率不要超过,13W,因为他把MOS集成进去了,所以存在一个散热问题,早些前IR也这样做过,但始终不成功.现在只有FSC可以做到这样.
我在调试时也是会烧,调功率输出是否调节LCC的参数,LCC参数与工作频率的关系是什么,我是刚接触灯这一个行业.还有市面上的灯灯功率好像与标称相差很远.我们在市面上买回来55W~H管测试总功率只有28W,灯功率27W这正常吗?

FAN7710集成了半桥驱动和功率开关管,设计起来比较方便.如果在多次上电的时候烧片子,请调整一下自举回路的参数试试,如图示.特别是自举电容,一般来讲容值大一些会好一些,此外自举二极管要使用快恢复二极管.

那还不如试试NXP半导体的UBA2024P,呵呵!

请问FAN7710这个料最大功率AC120V输入能做多少瓦? AC230V输入能做多少瓦?
另外问问飞兆公司有没推出适合电子镇流器和电子节能灯上用的低压三极管,如有型
号是什么?

Description
The FAN7710, developed using Fairchild’s unique highvoltage
process and system-in-package (SiP) concept, is
a ballast control integrated circuit (IC) for a compact
fluorescent lamp (CFL). The FAN7710 controls internal
high-voltage stress and delivers 20W to the lamp at
310VDC voltage. FAN7710 incorporates a preheating /
ignition function, controlled by an user-selected external
capacitor, to increase lamp life. The FAN7710 detects
switch operation from after ignition-mode through an
internal active Zero-Voltage Switching (ZVS) control
circuit. This control scheme enables the FAN7710 to
detect an open-lamp condition, without the expense of
external circuitry, and prevents stress on MOSFETs. The
high-side driver built into the FAN7710 has a commonmode
noise cancellation circuit that provides robust
operation against high-dv/dt noise intrusion.
