Adjustable DC-DC Buck Regulator, 4.5V-42V In, 34V Out, 600mA, TSOT-23-6

The Adjustable DC-DC Buck Step Down Regulator from Texas Instruments offers reliable power conditioning from unregulated sources. Featuring a wide input voltage range of 4.5V to 42V and an adjustable output ranging from 765mV to 34V, this regulator is highly versatile for various electronic applications. It delivers a maximum output current of 600mA.

Designed for maximum efficiency, the device includes a low RDSON internal switch of 0.9Ω typical, achieving up to 85% typical efficiency. The high switching frequency of 1.25MHz allows for the use of small external components while maintaining low output voltage ripple. Soft-start functionality can be implemented using the shutdown pin with an external RC circuit, enabling tailored soft-start times for specific needs.
