4.5V to 28V Input, 2.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9E202FP4-Z
4.5V to 28V Input, 2.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9E202FP4-Z is a single synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. The Light Load Mode control provides excellent efficiency characteristics in light-load conditions, which make the product ideal for equipment, and devices that demand minimal standby power consumption. BD9E202FP4-Z is a current mode control DC/DC converter and features good transient response. It includes internal phase compensation. It achieves the high power density and offers a small footprint on the PCB by employing small package.

背景
近年來，隨著消費性電子和工業設備應用產品功能的增加，對節省電路板空間的要求也越來越嚴格，小型DC-DC轉換器IC的使用率也與日俱增。另外，降低待機功耗已成為亟需解決的一大課題，也因此要求DC-DC轉換器IC在低功率（輕載）時實現更高效率。為了滿足上述市場需求，ROHM推出比現有SOP-J8封裝產品更小、效率更高的產品。
概要
本產品的輸出電流為1A～3A，並且全部採用小型SOT23封裝尺寸（2.8mm×2.9mm）。與市場上的SOP-J8（JEDEC標準：相當於SOIC8）封裝（4.9mm×6.0mm）產品相比，本產品安裝面積減少約72%，非常有助電源的小型化。此外，透過無線結構封裝，還降低了導線阻抗（佈線的電阻分量），實現高效工作。
應用範例
消費性電子：冰箱、洗衣機、空調等
工業設備：PLC（Programable Logic Controller）、逆變器、AC伺服器 等
