42VIN Micropower No-Opto Isolated Flyback Converter with 65V/3.6A Switch

DESCRIPTION The LT?8302/LT8302-3 is a monolithic micropower isolated flyback converter. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no third winding or opto-isolator for regulation. The output voltage is programmed with two external r

副邊同步整流器驅(qū)動(dòng)器

LT?8309 是一款副邊同步整流器驅(qū)動(dòng)器，其可取代反激式拓?fù)渲械妮敵稣髌鞫O管。通過用一個(gè) N 溝道 MOSFET 替代該二極管，應(yīng)用電路將不再受輸出二極管熱限制條件的約束。該 IC 通過檢測(cè)漏極至源極電壓以確定電流在什么時(shí)候變至負(fù)值，從而復(fù)制了二極管的運(yùn)行方式。LT8309 低的最小導(dǎo)通和關(guān)斷時(shí)間有助改善抗噪聲性能。\n\n 26ns 的快速傳播延遲使得應(yīng)用電路能夠在不連續(xù)導(dǎo)通模式 (DCM) 和臨界導(dǎo)通模式 (CrCM) 中運(yùn)作。柵極驅(qū)動(dòng)器具有一個(gè)用于實(shí)現(xiàn)快速關(guān)斷的 0.8Ω 下拉器件。40V VCC 額定值允許器件采用 MOSFET 的輸出電壓或整流漏極電壓來驅(qū)動(dòng)。400μ ? 可采用 DCM 和 BCM/CrCM 導(dǎo)通模式反激拓?fù)鋅n\n?
