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 (IOUT) 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 (fSW). 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 (VOUT) at load currents up to 2.2A, from a 5V to 36V input voltage (VIN) range.
The MPQ4432 is available in a QFN-16 (3mmx4mm) package.
