... The Future of Analog IC Technology DESCRIPTION The MP3209 is a current mode step up converter intended for small, 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 ...

... This results in more current to flow through the power MOSFET, thus increasing the power delivered to the output. The MP3209 has internal soft start to limit the amount of input current at startup and to also limit the amount of overshoot on the output. The current limit is increased by a fourth every 40µs giving a total soft start time of 120µ ...
