EVQ4431-L-00A

EVQ4431-L-00A evaluation board is designed to demonstrate the capabilities of the MP4431 and the MPQ4431. The MPQ4431 is a frequency-configurable (350KHz to 2.5MHz), synchronous, step-down switching regulator with integrated, internal high-side and low-side power MOSFETs. It provides up to 1A of highly efficient output current with current mode control for fast loop response. The MPQ4431 employs advanced asynchronous mode (AAM) to achieve high efficiency under light-load conditions by scaling down the switching frequency. This reduces the switching and gate driving losses. The EVQ4431-L-00A is a fully assembled and tested evaluation board, it generates 3.3V of output voltage at load currents up to 1A from a 3.3V to 36V input voltage range with 450KHz switching frequency. The MPQ4431 is available in a QFN-16 (3mmx4mm) package. Typically used in automotive systems and industrial power systems.
