Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the obsolete status of this component before procurement. The datasheet indicates the product has been discontinued by Fairchild Semiconductor. Confirm availability through authorized distributors or secondary markets, as standard production supply is no longer active. Ensure compatibility with replacement parts if necessary.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component only if legacy support for the Fairchild FAN5631 series is required. Consider its 1.5MHz switching frequency and 250mA output capability when designing circuits. Evaluate alternative modern equivalents due to discontinuation status. Verify package compatibility with the 10-MLP footprint during PCB layout.

Voltage Regulators - DC DC Switching Regulators Part Context

The FAN5631MPX belongs to the FAN5631/FAN5632 family of regulated step-down charge pumps from Fairchild Semiconductor. These devices are part of the Power Management IC (PMIC) category, specifically DC-DC switch regulators. The MPX suffix denotes the specific 10-MLP packaging variant with an exposed pad for thermal performance.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, consult manufacturer recommendations for direct replacements or evaluate generic charge pump alternatives with similar 1.5MHz frequency and 250mA output specifications.
