BL9384B中文资料降压型DC/DC转换器：20V,3A,同步降压,轻载高效数据手册Belling规格书

描述 Description

The BL9384B is a wide input range, high efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 3A of output current. Current mode PWM control allows the use of small external components, such as ceramic input and output caps, as well as small inductors, while still providing low output ripples. On top of the integrated internal synchronous rectifier that eliminates external Schottky diode, Overall BL9384B is a highly efficient and robust solution for DC-DC step-down applications that requires wide input ranges. BL9384B is available ESOP8 Packages.
