MPS 5安培大电流的DCDC芯片  MP4470  MP994313828760986 赵工

The MP4470/4470A is a fully-integrated, high-frequency, synchronous, rectified, step-down switch-mode converter. The device offers a very compact solution to achieve *** of continuous output current (IOUT) across a wide input supply range with excellent load and line regulation. It also provides fast transient response and excellent stability across the wide input supply and load range.

The MP4470/4470A operates at high efficiency across a wide output current load range. The MP4470 has full protection features, including short-circuit protection (SCP), over-current protection (OCP), over-voltage protection (OVP) with latch, under-voltage protection (UVP), and thermal shutdown. The MP4470A has the same protection features as the MP4470, but it does not have an OVP latch function.

The MP4470/4470A requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-20 (3mmx4mm) package.
