AP62600
4.5V TO 18V INPUT, 6A SYNCHRONOUS BUCK CONVERTER
Pin Assignments
The DIODES™ 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-side power MOSFET and a 14mΩ low-side power
MOSFET to provide 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)
control to achieve fast transient response, easy loop stabilization, and
low output voltage ripple.

The AP62600 design is optimized for Electromagnetic Interference
(EMI) reduction. The device has a proprietary gate driver scheme to
resist switching node ringing without sacrificing MOSFET turn-on and
turn-off time, which reduces high-frequency radiated EMI noise
caused by MOSFET switching.
