The EVQ4432-L-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4432 and the MPQ4432-AEC1. The MPQ4432 is a configurable-frequency (350kHz to 2.5MHz), synchronous, step-down switching regulator with integrated, internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively). It provides up to 2.2A of highly efficient output current (I_OUT) with current mode control for fast loop response.

The MPQ4432 employs advanced asynchronous modulation (AAM) mode to achieve high efficiency under light-load conditions by scaling down the switching frequency (f_SW). This reduces the switching and gate driving losses.

The EVQ4432-L-00A is a fully assembled and tested evaluation board that generates 5V of output voltage (V_OUT) at load currents up to 2.2A, from a 5V to 36V input voltage (V_IN) range.

The MPQ4432 is available in a QFN-16 (3mmx4mm) package.
