General Description
APW7312 is a 2A synchronous buck converter with inte-
grated power MOSFETs. The APW7312 design with a cur-
rent-mode control scheme, can convert wide input volt-
age of 4.5V to 24V to the output voltage adjustable from 0.
925V to 20V to provide excellent output voltage regulation.
The APW7312 is equipped with an automatic PFM/PWM
mode operation. At light load, the IC operates in the PFM
mode to reduce the switching losses. At heavy load, the
IC works in PWM.
The APW7312 is also equipped with Power-on-reset, soft-
start, soft-stop, and whole protections (under-voltage,
over-temperature, and current-limit) into a single package.
This device, available SOP-8, provides a very compact
system solution external components and PCB area.
