APW7302 is a 2A synchronous buck converter with inte-

grated power MOSFETs. The APW7302 design with a

current-mode control scheme, can convert wide input

voltage of 4.5V to 24V to the output voltage adjustable

from 0.92V to 20V to provide excellent output voltage

regulation.

The APW7302 is also equipped with Power-on-reset, soft-

start, and whole protections (over-temperature, and cur-

rent-limit) into a single package.

This device, available SOP-8, provides a very compact

system solution external components and PCB area.
