The MP4423C is a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve up to 6A of continuous output current (IOUT), with excellent load and line regulation across a wide input supply range. The MP4423C provides synchronous mode to achieve higher efficiency across the IOUT load range.\n\n Current mode provides fast transient response and eases loop stabilization. Fault condition protections include current limiting with hiccup mode, output over-voltage protection (OVP), and thermal shutdown (TSD).\n\n The MP4423C requires a minimal number of readily available, standard external components. It is available in a QFN-16 (3mmx4mm) package.\n\n
