Step-down Converters Requiring High Efficiency
and 2A Output Current
The APW7085 is a 2A, asynchronous, step-down con-
verter with integrated 100mP-channel MOSFET. The
device, with current-mode control scheme, can convert
4.5~26V input voltage to the output voltage adjustable
from 0.8 to 90% VIN to provide excellent output voltage
regulation.
The APW7085 regulates the output voltage in automatic
PSM/PWM mode operation, depending on the output
current, for high efficiency operation over light to full load
current. The APW7085 is also equipped with power-on-
reset, soft-start, and whole protections (under-voltage,
over- temperature, and current-limit) into a single package.
In shutdown mode, the supply current drops below 5µA.
This device, available in an 8-pin SOP-8 package, pro-
vides a very compact system solution with minimal exter-
nal components.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which
are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for
MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen
free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by
weight).
