有幾個問題想請教一下.
我最近用7710點了一個13W雙U型燈管和22W的環型燈管.
出現的問題是重新上電的時候 會出現7710燒毀的情況.
不知道問題出在哪里.有沒有類似經驗的人能指導一下
小弟萬分感謝!
有人用FAN7710做個低功率的節能燈嗎?

FAN7710是FSC2005年在韓國研發,2006年在中國華南地區發布,首先是找CETZGE做了首次測試,中間出現過燒機的問題,后來又經過調試,其保護功能很強大,設計的時候注意功率不要超過,13W,因為他把MOS集成進去了,所以存在一個散熱問題,早些前IR也這樣做過,但始終不成功.現在只有FSC可以做到這樣.
我在調試時也是會燒,調功率輸出是否調節LCC的參數,LCC參數與工作頻率的關系是什么,我是剛接觸燈這一個行業.還有市面上的燈燈功率好像與標稱相差很遠.我們在市面上買回來55W~H管測試總功率只有28W,燈功率27W這正常嗎?

FAN7710集成了半橋驅動和功率開關管,設計起來比較方便.如果在多次上電的時候燒片子,請調整一下自舉回路的參數試試,如圖示.特別是自舉電容,一般來講容值大一些會好一些,此外自舉二極管要使用快恢復二極管.

那還不如試試NXP半導體的UBA2024P,呵呵!

請問FAN7710這個料最大功率AC120V輸入能做多少瓦? AC230V輸入能做多少瓦?
另外問問飛兆公司有沒推出適合電子鎮流器和電子節能燈上用的低壓三極管,如有型
號是什么?

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.
