Product Description

The MP3425 is a current mode step‑up converter with a 3.5A, 90mΩ internal switch to provide a highly efficient regulator with fast response. The MP3425 operates at a programmed fix frequency up to 2MHzallowing for easy filtering and low noise. An external compensation pin gives the user flexibility in setting loop dynamics, whichallows the use of small, low‑ESR ceramic output capacitors. Soft-start results in smallinrush current and can be programmed with an external capacitor. The MP3425 operates from an input voltage as low as 3.0V and can generate 48V at up to 350mA from a 12V supply.

The MP3425 includes under-voltage lockout, current limiting and thermal overload protection to prevent damage in the event of an output overload. The MP3425 is available in a low profile 14-pin QFN package with exposed pad.
