The Future of Analog IC Technology MP3120 1.2A, 1.1MHz Synchronous Boost Converter with Output Disconnect DESCRIPTION The MP3120 is a high efficiency synchronous, current mode step-up converter. The device can boost a single cell or two cells AA battery up to 5V. The MP3120 can start up from an input voltage as low as 0.8V and provide in-rush current limiting as well as output short circuit protection. The integrated P-Channel synchronous rectified switch provides improved efficiency and eliminates the need of an external schottky diode. The P-MOS will disconnect the output from the input when EN is low. This output disconnect feature allows the output to be pletely discharged, thus...
