STI3508CA数据手册Tollsemi中文资料规格书

描述 Description

The STI3508C and STI3508CA are constant frequency, peak current mode step-up converter with SOT23-6 package intended for small, low power applications. The STI3508C and STI3508CA switch at 1.2MHz and allow 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 and STI3508CA devices feature automatic shifting to pulse frequency modulation mode at light loads. The STI3508C and STI3508CA include under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The STI3508C and STI3508CA are available in a small SOT23-6 package.
