Description

The AP64203Q is an adjustable switching frequency, internally compensated, synchronous DC-DC buck converter with a default internal frequency of 500kHz. The device fully integrates a 185mΩ high-side power MOSFET and an 80mΩ low-side power MOSFET to provide highly efficient step-down DC-DC conversion.
