... The Future of Analog IC Technology DESCRIPTION The MP1541 is a 5-pin thin SOT23 current mode step up converter intended for small, low power applications. The MP1541 switches at 1.3MHz 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 ...

... This results in more current to flow through the power MOSFET, thus increasing the power delivered to the output. The MP1541 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 ...
