GENERAL DESCRIPTION

The STI3508 is a constant frequency, 6

SOT23 current mode step

intended for small, low power applications.

The STI3508 switches at 1MHz and allows

the use of tiny, low cost capacitors and

inductors 2mm or less in height. Internal

soft-start results in small inrush current and

extends battery life.

The STI3508 features automatic shifting to

pulse frequency modulation mode at light

loads. The STI3508 includes under

lockout, current limiting, and thermal

overload protection to prevent damage in

the event of an output overload. The

STI3508 is available in a small 6

package.
