General Description
The APW7142 is a 3A synchronous-rectified Buck converter with integrated 70mW
power MOSFETs. The APW7142, designed with a current-mode control scheme, can
convert wide input voltage of 4.3V to 14V to the output voltage adjustable
from 0.8V to VIN to provide excellent output voltage regulation.
For high efficiency over all load current range, the APW7142 is equipped with
an automatic Skip/PWM mode operation. At light load, the IC operates in the
Skip mode, which keeps a constant minimum inductor peak current, to reduce
switching losses. At heavy load, the IC works in PWM mode, which inductor peak
current is programmed by the COMP voltage, to provide high efficiency and
excellent output voltage regulation.
The APW7142 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. In shutdown mode, the supply current drops below
3μA.
This device, available in a 8-pin SOP-8 package, provides a very compact
system solution with minimal external components and PCB area.
