輸入電壓2.7V至5.5V，內建4.0A MOSFET單路同步降壓DC-DC轉換器
BD9B406ANF-Z是BD9Bx06NF-Z系列單路同步降壓DC-DC轉換器之一，內建低導通電阻功率MOSFET。其最大輸出電流可達4A。由於參考電壓為±1%，因此輸出電壓可達到高精度。採用恆定導通時間控制系統，具有快速瞬態響應。輕載模式控制可提高輕載條件下的效率。非常適合降低設備的待機功耗。Power Good功能可讓系統進行時序控制。採用6接腳1.5mm x 1.5mm小型封裝，實現了高功率密度並在PCB上佔用較小的空間。 我們也提供具有輕載模式控制的產品系列以及不同輸出電流的產品。
本產品不建議使用的車載設備。

- Evaluation Board - BD9B406ANF-EVK-001
This Evaluation Board was developed for ROHM's Single Synchronous Buck DC/DC Converter BD9B406ANF-Z. BD9B406ANFZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. The output voltage can achieve a high accuracy due to ±1 % reference voltage. It features fast transient response due to constant on-time control system. The Light Load Mode control improves efficiency in light-load conditions. It is ideal for reducing standby power consumption of equipment. Power Good function makes it possible for system to control sequence. It achieves high power density and offers a small footprint on the PCB by employing 6 pins in a 1.5 mm x 1.5 mm small package.
