MP3213 Datasheet | Monolithic Power Systems

DESCRIPTION The MP3213 is a current mode step-up converter with a 3.5A, 0.18Ω internal switch to provide a highly efficient regulator with fast response. The MP3213 operates at 700KHz or 1.3MHz allowing for easy filtering and low noise. An external pensation pin gives the user flexibility in setting loop dynamics, which allows the use of small, low-ESR ceramic output capacitors. Soft-start results in small inrush current and can be programmed with an external capacitor. The MP3213 operates from an input voltage as low as 2.5V and can generate 12V at up to 500m A from a 5V supply. The MP3213 includes under-voltage lockout, current limiting and thermal overload protection to prevent damage in the event of an output overload. The MP3213 is available in a low profile 8-pin MSOP and 10-pin QFN package with exposed pad.
