Kit details

The EV4430-L-00A is an evaluation board for the MP/MPQ4430GL.

MP/MPQ4430GL 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 3.5A highly efficient output current with current mode control for fast loop response.

The MP/MPQ4430GL 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 EV4430-L-00A is a fully assembled and tested evaluation board, it generates +3.3V output voltage at load current up to 3.5A from a 3.3V to 36V input range.
