APW7314 is a 2A synchronous buck converter with inte-
grated low Rds(on) power MOSFETs. The APW7314 de-
sign with a current-mode control scheme, can convert
wide input voltage of 4.5V to 24V to the output voltage
adjustable from 0.807V to 13V to provide excellent output
voltage regulation.
The APW7314 is also equipped with Under-voltage
lockout, soft-start, over-temperature and current-limit pro-
tection into a single package.
This device, available TSOT-23-8A, provides a very com-
pact system solution external components and PCB area.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
