Description

The EV4431-L-00A is an evaluation board for the MP/MPQ4431GL.

MP/MPQ4431GL is a frequency programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated internal high-side and low-side power MOSFETs. It provides up to 1A highly efficient output current with current mode control for fast loop response.

The MP/MPQ4431GL employs AAM (Advanced Asynchronous Modulation) mode which helps to achieve high efficiency at light load condition by scaling down the switching frequency to reduce the switching and gate driving losses.

The EV4431-L-00A is a fully assembled and tested evaluation board, it generates +3.3V output voltage at load current up to 1A from a 3.3V to 36V input range.
