DESCRIPTION
The MP4415A is a high-frequency,
synchronous, rectified, step-down, switch-mode
converter with built-in power MOSFETs. The
MP4415A offers a very compact solution that
achieves 1.5A of continuous output current with
excellent load and line regulation over a wide
input supply range. The MP4415A uses
synchronous mode operation for 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 MP4415A requires a minimal number of
readily available, standard external
components, and is available in a space-saving
QFN-13 (2.5mmx3mm) package.
