BL9341中文资料降压型DC/DC转换器：40V,0.6A,同步降压,轻载高效数据手册Belling规格书

描述 Description

The BL9341 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the BL9341 delivers 600mA of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in low frequency to maintain high efficiency and low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit. The BL9341 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The BL9341 is available in 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
