AP64203Q 3.8V TO 40V INPUT AUTOMOTIVE GRADE, 2A LOW IQ SYNCHRONOUS BUCK CONVERTER 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. The AP64203Q enables continuous load current of up to 2A with as high as 95% efficiency. The device features current mode control operation, enabling easy loop stabilization, and supports a wide range of output capacitive loads. With its high level of integration and minimal need for external components, the AP64203Q simplifies board layout and reduces space requirements.
