BM1Q002AFJ-LB
准谐振DC-DC转换器

本产品是能够保证向工业设备市场长期供应的产品,而且是非常适用于这些应用领域的产品。准谐振控制器型DC-DC转换器IC BM1Q0xxAFJ-LB可为带插座的产品提供理想的系统。采用准谐振工作模式,可实现软开关,有助于降低EMI。由于其开关MOSFET和电流检测电阻是外置的,因此可使电源设计的灵活性更高。本IC内置启动电路,有助于降低待机功耗和提高启动速度。在轻负载时,由于内置Burst功能而且IC的静态电流很低,因此可降低待机功耗。另外,本产品还内置软启动功能、Burst功能、以及逐周期过电流保护、过电压保护、过负载保护、CS开路保护等多种保护功能,因此安全性非常优异。
