TS33010中文资料开关调节器数据手册Semtech规格书

描述 Description

The TS33010 is a DC/DC synchronous switching regulator with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 2.25MHz enables the use of extremely small filter components, resulting in smaller board space and reduced BOM costs.
