STI3508/B数据手册Tollsemi中文资料规格书

描述 Description

The STI3508 is a constant frequency, 6-pin SOT23 current mode step-up converter 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-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The STI3508 is available in a small SOT23-6 package.
