NXP i.MX 7Solo/7Dual用電源管理IC
BD71815AGW憑藉羅姆出眾的模擬設計技術實現了“i.MX 7Solo/7Dual”處理器驅動的最佳電源系統。它不僅擁有與以往產品同等的功率轉換效率（82%以上），還成功將待機時的電流消耗減少了16％※1，這是在應用中實現低功耗的關鍵。此外，還內建了30V耐壓的帶輸入過電壓保護功能（OVP）的Li-ion電池充電器和LED驅動器（6燈）。由於開關頻率高速化（6MHz）實現的外接線圈的小型化、搭載功能的優化、以及採用WL-CSP的小型封裝（16mm²： 面積比以往減少75％）的應用，使得包含外接零件在內的貼裝面積大幅度減少。內建庫侖計數器，採用搭載羅姆獨創演算法的參考軟體，實現了高精度電池餘量監視。本產品對移動設備所追求的“低功耗”、“小型化”、“高精度”做出了很大貢獻。
