Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific output voltage variant (3.6 V, 5 V, or 5.45 V) required for your design, as these are distinct part numbers within the same series. Confirm the WLCSP-9 package compatibility with your PCB footprint. Ensure the input voltage range aligns with your source supply. Check for RoHS compliance documentation if required by your manufacturing standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a synchronous boost solution is needed for inputs between 2.5 V and 5.5 V. The 800 mA output current suits moderate load applications. Consider the 2.5 MHz frequency for balancing component size and efficiency. The low quiescent current makes it suitable for battery-operated systems where standby power consumption is critical.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN48685 series of TinyBoost regulators. It shares the synchronous boost architecture and WLCSP-9 packaging with other variants in the family, differing primarily in fixed output voltage settings. The series targets portable electronics requiring small form factors and high efficiency.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other FAN48685 variants with different fixed output voltages (e.g., FAN48685UC05X for 5 V). Cross-family replacements require matching input/output specifications and package type.
