General Description
APW7153/A/B is a 3A synchronous buck converter with
integrated 110mΩ power MOSFETs. The APW7153/A/B
is designed with a current-mode control scheme; it can
convert wide input voltage of 2.6V to 5.5V to the output
voltage adjustable from 0.8V to 5.5V to provide excellent
output voltage regulation.
The APW7153/A/B is equipped with an 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. At PWM mode, the switching frequency is set by
the external resistor.
The APW7153/A/B 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 TDFN3x3-10 and SOP-8P provides
a very compact system solution external components and
PCB area.
