The MP1540 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. The MP1540 operates from an input voltage as low as 2.5V and can generate 12V at up to 200mA from a 5V supply.  \nThe MP1540 includes under voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MP1540 is available in a small 5-pin TSOT23 package.  \nFEATURES  \n• On Board Power MOSFET  \n• Uses Tiny Capacitors and Inductors  \n• 1.3MHz Fixed Switching Frequency  \n• Internal Soft-Start  \n• Operates with Input Voltage as Low as  \n2.5V and Output Voltage as High as 18V  \n• 12V at 200mA from 5V Input  \n• UVLO, Thermal Shutdown  \n• Internal Current Limit  \n• Available in a TSOT23-5 Package  \nAPPLICATIONS  \n• Camera Phone Flash  \n• Handheld Computers and PDAs  \n• Digital Still and Video Cameras  \n• External Modems  \n• Small LCD Displays  \n• White LED Driver  \n“MPS”and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.  \nTYPICAL APPLICATION  \nVIN  \n5V  \nOFF ON  \n100  \nEFF IC IENCY (%)  \n95  \n90  \n85  \n80  \n75  \n70  \n65  \n60  \n55  \n50  \nEfficiency vs Load Current  \n\n|  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- |\n| | | | VIN\u003Cbr>| = 5V |  |\n| | | | | | |\n| | |  | | | |\n| | VIN = | 3.3V |  | \u003Cbr>= 4 | 2V |\n| |  |  |  | IN | . |\n| |  |  |  |  |  |\n|  |  |  |  |  |  |\n|  |  |  |  |  |  |\n|  |  |  |  |  |  |\n\nV  \n0 75 150 225 300 375 450  \nLOAD CURRENT (mA) MP1540_TAC_EC01  \nMP1540 Rev. 1.0 [www.MonolithicPower.com](www.MonolithicPower.com) 1  \n8/15/2005 MPS Proprietary Information.
