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.
