RT7264EZQW

Voltage Regulators - DC DC Switching Regulators Overview

The Richtek RT7264EZQW is a synchronous step-down DC-DC converter featuring an adjustable output voltage range from 0.808V to 15V and a maximum output current of 4A. It operates with an input voltage supply between 4.5V and 21V at a fixed switching frequency of 500kHz. The device integrates internal power MOSFETs for high efficiency and is housed in a compact 14-WDFN (4x3) package with an exposed pad for thermal management, suitable for surface mount installation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'EZQW' against the manufacturer's official datasheet to confirm exact packaging specifications and tape-and-reel quantities. Ensure the component matches the required 14-WDFN footprint and thermal pad dimensions for PCB layout compatibility. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output synchronous regulator is needed for applications requiring up to 4A load current. The 500kHz switching frequency offers a balance between component size and efficiency. Ensure the input voltage remains within the 4.5V to 21V range and that the thermal design supports the 14-WDFN package dissipation characteristics for the intended operating environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the Richtek RT7264 series of synchronous step-down converters. The series is designed for space-constrained applications, offering high integration by combining control logic and power switches in a small form factor. The RT7264EZQW specifically denotes the version packaged in the 14-WDFN format, distinguishing it from other pinout or package variants within the same functional family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for direct pin-compatible alternatives such as the RT7264AZSP if a PSOP-EP package is acceptable. Verify that any substitute maintains the 4A current rating, 21V max input, and 500kHz frequency to ensure circuit performance consistency without redesigning the passive components.
