EVQ4430-L-00A

Evaluation board is designed to demonstrate the capabilities of the MP4430 and the MPQ4430. The MPQ4430 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 3.5A of highly efficient output current with current mode control for fast loop response. The MPQ4430 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 EVQ4430-L-00A is a fully assembled and tested evaluation board. It generates 5V of output voltage at load currents up to 3.5A, from a 5V to 36V input voltage range. The MPQ4430 is available in a QFN-16 (3mmx4mm) package. Typical applications includes automotive systems and industrial power systems.
