Applications
APW7511 is a 3A synchronous buck converter with inte-
grated low R DS(ON) power MOSFETs. The APW7511 de-
sign with a current-mode control scheme, can convert
wide input voltage of 4.5V to 24V to the output voltage
adjustable from 0.807V to 13V to provide excellent output
voltage regulation.
The APW7511 is equipped advance asynchronous modu-
lation mode operation. Increase efficiency at light load.
The APW7511 is also equipped with Power-on-reset, soft
start, and whole protections (under-voltage,
over-temperature, and current-limit) into a single package.
This device, available TSOT-23-8A, provides a very com-
pact system solution external components and PCB area.

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