高效同步3.5A降壓升壓變換器帶四個(gè)集成MOSFET

SC8723是一款集成四開關(guān)的同步升降壓變換器。 無論輸出電壓高、低或等于輸入電壓，都能提供高效的電源效率和穩(wěn)定的電壓調(diào)節(jié)。 SC8723支持非常寬的輸入和輸出電壓范圍。輸入電壓范圍能夠達(dá)到2.7V至22V，輸出電壓范圍能夠達(dá)到3V至22V，并且支持最高3.5A的輸出電流。SC8723采用平均電流模式控制。 輸出電壓由FB引腳上的電阻來調(diào)節(jié)。 芯片工作模式(PSM /FPWM)和開關(guān)頻率均可通過外部設(shè)置進(jìn)行調(diào)整。 該芯片還提供了可編程的輸出電流限制，靈活支持不同的應(yīng)用。 SC8723支持內(nèi)部限流、輸入欠壓保護(hù)、輸出過壓保護(hù)、輸出短路保護(hù)、FB短路保護(hù)、過溫保護(hù)，確保在不同異常情況下的安全。 S 高效率升降壓轉(zhuǎn)換\n\n極簡(jiǎn)的外圍器件\n\n集成四個(gè)低RDS(ON)開關(guān)管\n\n超寬的輸入范圍：2.7V至22V\n\n超寬的輸出范圍：3.0V至22V\n\n支持固定5.1V的輸出電壓\n\n支持3.5A的輸出電流\n\n支持250K/500K/750K/1MHz開關(guān)頻率可調(diào)\n\n支持輸出限流可調(diào)\n\n支持強(qiáng)制PWM模式/ PSM模式可選\n\n支持EN控制和可編程UVLO\n\n內(nèi)部軟啟動(dòng)\n\n支持輸入輸出過電壓保護(hù)\n\n輸出短路保護(hù)打嗝模式\n\n熱關(guān)斷保護(hù)\n\n欠壓保護(hù)\n\n過壓保護(hù)\n\nQFN-22 FC 3 x 3封裝;
