The MPQ3425 is a current-mode, step-up converter with a 3.5A, 90mΩ internal switch that provides a highly efficient regulator with fast response. The MPQ3425 features a programmed frequency of up to 2MHz that provides easy filtering and low noise. An external compensation pin allows for flexibility in setting loop dynamics and operates with small, low-ESR ceramic output capacitors. The soft start feature provides a small inrush current and can be programmed with an external capacitor. The MPQ3425 operates with an input voltage as low as 3.1V, and can generate 48V at up to 350mA from a 12V supply.
Full protection features include under-voltage lockout (UVLO), current limiting, and thermal overload protection. The MPQ3425 is available in a low-profile QFN-14 (3mmx4mm) package with an exposed pad.

EVQ3425-L-00A Evaluation Kit Boost Converter With a 55V, 3.5A Switch
The MPQ3425 is a current mode step‑up converter with a 3.5A, 90mΩ internal switch to provide a highly efficient regulator with fast response. The MPQ3425 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 MPQ3425 includes under-voltage lockout, current limiting and thermal overload protection to prevent damage in the event of an output overload. The MPQ3425 is available in a low profile 14-pin QFN package with exposed pad.
