Procurement Notes
Verify the specific datasheet version and ordering information directly with authorized distributors or the manufacturer. Confirm that the 14-WDFN (3x2) package matches your PCB footprint requirements. Ensure compatibility with the 3V to 26V input range and 560kHz switching frequency for your design. Check for any specific handling or storage instructions related to moisture sensitivity levels before assembly.
Selection Notes
Select this component when a single-phase synchronous buck controller is required with a wide input voltage range up to 26V. The 560kHz frequency offers a balance between size and efficiency. Consider the 14-WDFN package for compact designs. Verify thermal performance requirements against the package's dissipation capabilities. Ensure the target application aligns with the documented use cases such as Intel platform auxiliary rails.
Part Context
This part belongs to Richtek's line of high-efficiency switching controllers. It is specifically engineered for demanding applications like Intel processor power supplies. The WDFN package allows for space-constrained layouts. It complements other components in complete power solution designs for modern computing platforms.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout and electrical parameter compatibility before replacing. Cross-reference with similar single-phase buck controllers if availability is an issue.
