BD9G401UEFJ-M
1ch 降壓型開關穩壓器
本IC是內置高邊FET的二極管整流式降壓型開關穩壓器，支持在4.5V～42V的電源電壓範圍內工作。該產品通過電流模式控制實現了高速負載響應和簡單的相位補償設置。例如在小型二次側電源應用中，可以將12V、24V等電源降壓後輸出3.3V、5V等電壓。另外，該產品還具有與外部CLK同步的功能，可以進行噪聲管理。
本IC是為提高生產效率而對本系列產品中的BD9G401EFJ-M變更生產線後形成的型號，在新項目選型時，建議選擇該型號，在技術規格書中的保證特性並沒有差異。此外，由於文檔和設計模型等也沒有差異，因此除非另有說明，ROHM將公開BD9G401EFJ-ME2的數據。

This EVK is using not BD9G401UEFJ-M, but BD9G401EFJ-M. This EVK has been developed for ROHM’s non-synchronous buck DC/DC converter customers evaluating BD9G401EFJ-M. While the BD9G401EFJ-M accepts a power supply input range of 4.5V to 42V, and generates output voltages from 1V to VCC, this EVK is setup for the input voltage range of 10V to 42V and a fixed output of 5V can be produced.
