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 compensation 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 500mA from a 5V supply.
