TS33001 High Efficiency Synchronous 1/2/3A DC/DC Buck Converter

The TS33001/2/3 (1/2/3A) are DC/DC synchronous switching regulators with fully integrated power switches, internal compensation, and full fault protection. The switching frequency of 5MHz enables the use of extremely small filter components, resulting in smaller board space and reduced BOM costs. When the input current is greater than approximately 50mA, the.
