MP3120DJ - 1.1MHz Synchronous Boost Converter

Download the MP3120DJ datasheet PDF. This datasheet also covers the MP3120 variant, as both devices belong to the same 1.1mhz synchronous boost converter family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • an integrated power MOSFET that supports up to 5V output and a typical 1.2A switch current. The device also can maintain the output voltage regulated even when the input voltage is above the output voltage. The MP3120 is offered in a 6-lead ThinSOT23 package.

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 completely discharged, thus allowing the part to draw less than 1uA off current in shutdown mode. The 1.
