The MPQ4470/4470A is a fully-integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter. It offers a very compact solution to achieve a 5A, continuous-output current over a wide input-supply range with excellent load and line regulation. It also provides fast transient response and good stability for wide input-supply and load range..
include SCP, OCP, OVP latch, UVP, and thermal shutdown. MPQ4470A has the same protection features to MPQ4470 except has no OVP latch function. The MPQ4470/4470A requires a minimal number of readily-available, standard, external components, and is available in a space-saving 3mm×4mm, 20-pin, QFN package.
