38 V 2 A同步降壓開關(guān)穩(wěn)壓器，30 uA靜態(tài)電流

L6986是一款降壓單片開關(guān)穩(wěn)壓器，能夠提供高達(dá)2 A直流電。VREF 電壓介于 0.85?V 到 VIN 之間。由于P溝道MOSFET高壓側(cè)功率元件，該設(shè)備具有100%的占空比操作。寬輸入電壓范圍滿足5 V、12 V和24 V電源的規(guī)格低功耗模式”（LCM）是專為在空閑模式下處于活動狀態(tài)的應(yīng)用而設(shè)計的，因此它可以在輸出電壓紋波受控的輕負(fù)載下最大限度地提高效率。低噪聲模式”（LNM）使開關(guān)頻率恒定過載電流范圍，滿足低噪聲應(yīng)用規(guī)范。輸出電壓監(jiān)測儀管理任何數(shù)字負(fù)載（μC，F(xiàn)PGA）的重置相位。RST開路集電極輸出還可在開機(jī)階段實現(xiàn)輸出電壓排序。同步整流，設(shè)計用于中重負(fù)載下的高效率，開關(guān)頻率 ? 2 A DC輸出電流 \n? 4 V至38 V工作輸入電壓 \n? 低功耗模式或低噪音模式 \n? 輕載下30 μA IQ(LCM VOUT = 3.3 V) \n? 8 μA IQ-SHTDWN \n? 可調(diào)fSW（250 kHz - 2 MHz） \n? 輸出電壓從0.85 V到VIN可調(diào) \n? 嵌入式輸出電壓監(jiān)測儀? 同步 \n? 軟啟動時間可調(diào) \n? 內(nèi)部電流限制 \n? 過電壓保護(hù) \n? 輸出電壓排序 \n? 峰值電流模式架構(gòu) \n?
