MPQ4470AGL-P

The MPQ4470 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. The MPQ4470/4470A operates at high efficiency over a wide output current load range. MPQ4470 has full protection features 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.
