MP4415A集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

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.
