General Description
APW7303 is a 3A synchronous buck converter with inte-
grated power MOSFETs. The APW7303 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 APW7303 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-8P, provides a very compact
system solution external components and PCB area.
