Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'G' corresponds to the RoHS-compliant version and specific tape-and-reel packaging configuration required for your assembly line. Confirm that the 'A1' designation matches the intended output voltage setting or control interface requirements against the official datasheet before finalizing procurement orders to ensure compatibility with system design constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing space-constrained applications requiring high efficiency at light loads. The 1.5MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Ensure the desired output voltage falls within the adjustable range supported by the external resistor divider network. Verify that the load current requirements do not exceed the maximum rated output current specified in the electrical characteristics table.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the XC9287 series of synchronous buck converters. The 'A1' typically denotes a specific pinout or functional variant within the family, while 'HCPR' indicates the WLCSP package type. The 'G' suffix signifies environmental compliance. This series is engineered for low-noise performance and high integration, targeting modern consumer electronics where board space and power efficiency are critical design parameters.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements must match the 1.5MHz frequency, 5.5V max input, and WLCSP-6 package. Verify equivalent current handling capabilities and output voltage adjustability. Cross-reference pinouts carefully as minor variations exist between series revisions. Ensure thermal performance characteristics align with the target application's heat dissipation requirements.
