Monolithic Power Systems (MPS) EVQ4423C-L-00A Evaluation Board
Monolithic Power Systems (MPS) EVQ4423C-L-00A Evaluation Board is designed for the MPQ4423C, a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in power MOSFETs. This board provides a compact solution to achieve 6A of peak output current with excellent load and line regulation across a wide input supply range. The EVQ4423C-L-00A board fault protections include hiccup mode current limiting, output Over-Voltage Protection (OVP), and Thermal Shutdown (TSD). The MPQ4423C evaluation board is available in a QFN-16 (3mmx4mm) package. Typical applications include automotive infotainment, wireless charging, and USB PDs.
