MP3209概述
The
MP3209 is a current mode step up converter intended for small, low power applications. The
MP3209 switches at 1.4MHz and allows the use of tiny, low cost capacitors and inductors to achieve a solution less than 1mm in height. Internal soft start results in small inrush current and extends battery life. The
MP3209 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The
MP3209 is available in small 5¬pin TSOT23 and 2mm x 2mm ultra-thin QFN 8-pin packages.
