2.7V至5.5V輸入、2.0A整合MOSFET單同步降壓DC-DC轉換器
BD9B206ANF-Z為BD9Bx06NF-Z系列中的一款單同步降壓DC-DC轉換器，內建低導通電阻功率MOSFET。其可提供最高2A的電流。輸出電壓可透過±1%的參考電壓，達到高精準度。採用恆定導通時間控制系統，可實現快速暫態響應。輕負載模式控制提高了輕負載條件下的效率。是降低設備待機功耗的理想選擇。Power Good功能使系統能夠控制序列。它採用6腳位1.5mm x 1.5mm小型封裝，實現高功率密度並在PCB上佔用較小的面積。 我們還提供具有輕負載模式控制以及不同輸出電流的產品陣容。

- Evaluation Board - BD9B206ANF-EVK-001
This Evaluation Board was developed for ROHM's Single Synchronous Buck DC/DC Converter BD9B206ANF-Z. BD9B206ANFZ 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.
