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 resp***e. The MP3213 operates at 700kHz or 1.3MHz allowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting loop dynamics, which allows the use of ***all, low ESR ceramic output capacitors. Soft-start results in ***all 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 500mA 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 ***ailable in a low profile 8-pin MSOP package with exposed pad.
