Feature
The MP4470/4470A is a fully-integrated, high frequency, 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 MP4470/4470A operates at high efficiency over a wide output current load range. MP4470 has full protection features include SCP, OCP, OVP latch, UVP, and thermal shutdown. MP4470A has the same protection features to MP4470 except has no OVP latch Function.
The MP4470/4470A requires a minimal number of readily-available, standard, external components, and is available in a space-saving 3mm×4mm, 20-pin, QFN package.
