留個(gè)雅虎的郵箱吧,由于EN600652002版容量大,不能上傳,給我郵件alexliuwj@yahoo.com.cn

我只找到UL153第十一版,急求第十二版,不知哪位樓主能夠提供?

請問樓主有沒有UL153最新(第十二版)標(biāo)準(zhǔn)?急用,先謝謝了!

我司是光寶代理,目前推一款PWM控制IC:OB2268/9,可與崇貿(mào)SG6841LD7552替換,可做到功率60W,但性能更優(yōu)越,而且OP2269帶有頻率抖動(dòng)技術(shù),ESD,EMI性能優(yōu)越,保護(hù)功能齊全,有興趣朋友請與我聯(lián)系,我將提供全套資料給你參考.劉先生alexliuwj@yahoo.com.cn0755-81923506

請考慮用OP2269,PIN對PIN,并帶有頻率抖動(dòng)技術(shù),我們設(shè)計(jì)工程師沒遇到此問題,如需要樣品,請聯(lián)系:alex@highray.com0755-83256300
