AP62600 4.5V TO 18V INPUT, 6A SYNCHRONOUS BUCK CONVERTER Description Pin Assignments TOP VIEW
The AP62600 is a 6A, synchronous buck converter with a wide input voltage range of 4.5V to 18V. The device fully integrates a 36mΩ high-
D TR C N / C FB G V
side power MOSFET and a 14mΩ low-side power MOSFET to provide
SS
high-efficiency step-down DC-DC conversion.

The AP62600 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT)
PGND 1
control to achieve fast transient response, easy loop stabilization, and
SW
low output voltage ripple.
