TS30041 & TS30042 DC/DC Buck Regulators

Semtech TS30041 and TS30042 DC/DC Buck Regulators are designed for high-performance applications requiring up to 40V input range in a wide range of markets such as industrial, telecommunications, and consumer. These synchronous switching regulators include fully integrated power switches, internal compensation, and full fault protection. Semtech TS30041 and TS30042 DC/DC Buck Regulators offer a switching frequency of 1MHz. This enables the use of small filter components resulting in minimal board space and reduced costs.
