TS30011中文资料High Efficiency 1A Current-Mode Synchronous Buck DC/DC Converter, 1MHz数据手册Semtech规格书

描述 Description

The TS30011 (1A) is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 1MHz enables the use of small filter components resulting in minimal board space and reduced BOM costs.
