The EV4432-L-00A is an evaluation board for the MP/MPQ4432GL.
MP/MPQ4432GL 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 2.2A highly efficient output current with current mode control for fast loop response.
The MP/MPQ4432GL 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 EV4432-L-00A is a fully assembled and tested evaluation board, it generates +3.3V output voltage at load current up to 2.2A from a 3.3V to 36V input range.

The MP4432 is a synchronous, step-down, switching regulator with programmable frequency (350kHz to 2.5MHz) and integrated, internal, high-side and low-side power MOSFETs. The MP4432 provides up to 2.2A of highly efficient output current with current mode control for fast loop response.
The wide 3.3V to 36V input range accommodates a variety of step-down applications in automotive input environments. The MP4432 is ideal for battery-powered applications due to its extremely low quiescent current.
The MP4432 employs advanced asynchronous mode (AAM) to achieve high efficiency in light-load condition by scaling down the switching frequency to reduce switching and gate driving losses.
Standard features include soft start, external clock synchronization, enable control, and power good indication. High-duty cycle and low dropout mode are provided for automotive cold-crank.
Over-current protection (OCP) with valley-current detection is employed to prevent the inductor current from running away. Hiccup mode reduces the average current greatly in short-circuit condition. Thermal shutdown provides reliable and fault-tolerant operation.
The MP4432 is available in a QFN-16 (3mmx4mm) package.
