AP64203Q - 2A LOW IQ SYNCHRONOUS BUCK CONVERTER

General Description

The AP64203Q is an adjustable switching frequency, internally compensated, synchronous DC-DC buck converter with a default internal frequency of 500kHz.

Key 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. This makes it ideal for distributed power architectures. The AP64203Q is available in the standard Green U-QFN404016/SWP (Type UXB) package. Pin Assignments 16 15 14 BIAS 1 VCC 2 VIN 3 VIN 4 EPAD 5 6 7 GND FB SS/TR PG 13 12.

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.
