BD71850MWV
NXP i.MX 8M Nano Family用電源管理IC

BD71850MWV是運用羅姆長年累積的處理器用電源技術，匯集i.MX 8M Nano Family處理器所需的電源和功能的PMIC。內建了適用於i.MX 8M Nano Family的電源ON/OFF時序器，不僅實現小型化，還容易進行應用設計，有助大幅削減開發週期。

匯集了控制邏輯、降壓DC/DC轉換器（Buck Converter）6ch、LDO6ch，只需1顆晶片，即可向處理器，以及應用所需的DDR記憶體供電。而且還內建SDXC卡用1.8V/3.3V開關、32.768kHz晶體振盪器的緩存、各種保護功能（各電源系統的輸出短路、輸出過電壓、輸出過電流和熱關斷）。配備最高功率轉換效率為95%的降壓DC/DC轉換器，可在1 CELL 鋰離子電池到USB的大輸入電壓範圍（2.7V~5.5V）內工作，是適合i.MX 8M Nano Famil適用領域的PMIC。
