MPQ4423AGQ
DESCRIPTION The MPQ4423A is a high-efficiency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very pact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input supply range. The MPQ4423A uses synchronous mode operation to achieve higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown. The MPQ4423A requires a minimal number of readily available, standard, external ponents and is available in a pact QFN-8 (3mmx3mm) package.
