STI3508C数据手册Tollsemi中文资料规格书

描述 Description

The STI3508C is a constant frequency, peak current mode step-up converter with SOT23-6 package intended for small, low power applications. The STI3508C 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 STI3508C features automatic shifting to pulse frequency modulation mode at light loads. The STI3508C includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The STI3508C is available in a small SOT23-6 package.
