但(dan)IR2161提(ti)供軟啟(qi)動(dong)(dong)操作，可以(yi)(yi)避免(mian)浪涌電(dian)(dian)(dian)流產(chan)生。在燈啟(qi)動(dong)(dong)期(qi)間，IR2161輸出125kHz的(de)(de)(de)(de)高(gao)頻(pin)(pin)(pin)。由于系統(tong)(tong)中(zhong)輸出高(gao)頻(pin)(pin)(pin)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)T1初(chu)級漏感(gan)是(shi)固定的(de)(de)(de)(de)，在較(jiao)高(gao)的(de)(de)(de)(de)頻(pin)(pin)(pin)率(lv)(lv)下呈現較(jiao)高(gao)的(de)(de)(de)(de)阻抗，初(chu)級繞組上(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)較(jiao)低．致使變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)輸出電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)較(jiao)低，燈電(dian)(dian)(dian)流較(jiao)小，同時也避免(mian)了保護電(dian)(dian)(dian)路(lu)被(bei)觸發。約經(jing)1s的(de)(de)(de)(de)時間，電(dian)(dian)(dian)路(lu)以(yi)(yi)較(jiao)低頻(pin)(pin)(pin)率(lv)(lv)運行。在此過(guo)程中(zhong)，IC腳3外部電(dian)(dian)(dian)容(rong)CSD上(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)從OV增加到(dao)5V。當(dang)空載時，VCSD=OV，振(zhen)蕩器(qi)(qi)(qi)頻(pin)(pin)(pin)率(lv)(lv)約60kHz。在蕞大負(fu)載下，VCSD=5V，振(zhen)蕩器(qi)(qi)(qi)頻(pin)(pin)(pin)率(lv)(lv)約30kHz。當(dang)輸出短(duan)路(lu)時，大電(dian)(dian)(dian)流流過(guo)半(ban)(ban)橋(qiao)，被(bei)RCS感(gan)測(ce)。只要(yao)IC腳4(CS)上(shang)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)超(chao)過(guo)1V的(de)(de)(de)(de)門(men)限(xian)電(dian)(dian)(dian)平持續50ms以(yi)(yi)上(shang)的(de)(de)(de)(de)時間，系統(tong)(tong)將關(guan)閉。如(ru)(ru)果負(fu)載超(chao)過(guo)蕞大負(fu)載的(de)(de)(de)(de)50%，IC腳4上(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)將超(chao)過(guo)O5V較(jiao)低的(de)(de)(de)(de)門(men)坎電(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，在經(jing)0．5S之后，系統(tong)(tong)將關(guan)閉。不論(lun)是(shi)短(duan)路(lu)保護還(huan)是(shi)過(guo)載保護，都(dou)能(neng)自動(dong)(dong)復位。IR2161還(huan)提(ti)供過(guo)熱關(guan)閉功(gong)能(neng)。當(dang)芯片結溫(wen)超(chao)過(guo)135℃的(de)(de)(de)(de)過(guo)溫(wen)度限(xian)制值時，半(ban)(ban)橋(qiao)開(kai)關(guan)將停止工作，以(yi)(yi)避免(mian)MOSFET燒壞。電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)用(yong)途編輯電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)在傳統(tong)(tong)照(zhao)(zhao)明燈具中(zhong)的(de)(de)(de)(de)應(ying)用(yong)十分普遍(bian)，如(ru)(ru)日光燈、臺燈、節(jie)能(neng)燈、廣(guang)告燈等等幾乎(hu)都(dou)可以(yi)(yi)使用(yong)電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)，并(bing)且采(cai)(cai)用(yong)電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)之后，可以(yi)(yi)省(sheng)掉啟(qi)動(dong)(dong)器(qi)(qi)(qi)。在LED照(zhao)(zhao)明中(zhong)，新品也大都(dou)采(cai)(cai)用(yong)電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)。主要(yao)是(shi)電(dian)(dian)(dian)子變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)在變(bian)(bian)壓(ya)(ya)(ya)(ya)功(gong)能(neng)上(shang)，效率(lv)(lv)高(gao)、成本底。浙江平板變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)(qi)(qi)訂做價格
