General Description
APW7322/A is a synchronous buck converters with inte-
grated 85m Ω high side and 75m Ω low side power
MOSFETs. The APW7322/A with a current-mode control
scheme can convert wide input voltage of 2.9V to 6V to
the output voltage adjustable from 0.8V to 6V to provide
excellent output voltage regulation.
The APW7322/A is equipped with an automatic Skip/PWM
mode operation. At light load , the IC operates in the Skip
mode to reduce the switching losses. At heavy load, the
IC works in PWM mode.
The APW7322/A is also equipped with Power-on-reset,
soft start, soft-stop, and whole protections (under-voltage,
over-voltage, over-temperature and current-limit) into a
single package.
This device, available in SOP-8, TDFN3x3-10 packages,
provides a very compact system solution external com-
ponents and PCB area.
