Semtech TS33010

High Efficiency Synchronous 500mA DC/DC Buck Converter, 2.25Mhz

Add to Watch List

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.
