Product Description

The MPQ3426 is a current-mode step up converter with a 6A, 90mΩ internal switch that provides a highly efficient regulator with a fast response. The MPQ3426 features a programmable frequency of up to 2MHz that allows for easy filtering and reduces noise. An external compensation pin gives the user flexibility in setting loop dynamics, and uses small, low-ESR, ceramic output capacitors. Soft-start results in a small inrush current and can be programmed with an external capacitor. The MPQ3426 operates from an input voltage as low as 3.2V and can generate up to a 35V output.
The MPQ3426’s features include under-voltage lockout, current limiting, and thermal overload protection. The MPQ3426 is available in a low-profile 14-pin 3mm×4mm QFN package with an exposed pad.
