Procurement Notes
Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance and MSL rating before integration. Check for valid PCN documentation regarding manufacturing changes. Ensure supply chain stability as availability may be limited.
Selection Notes
Select this model for space-constrained designs requiring 3.3V rails from single-cell lithium batteries. Compare against FAN48630UC33X for identical electrical performance. Evaluate thermal requirements within the small WLCSP footprint. Consider bypass mode benefits if ripple sensitivity is critical.
Part Context
Part of the TinyBoost family designed for ultra-compact power solutions. Manufactured by onsemi using advanced CMOS processes. Targets applications needing high power density in minimal board area. Shares architectural similarities with other FAN48630 variants differing only in output voltage settings.
Replacement Considerations
FAN48630UC33X offers equivalent electrical specifications and pinout compatibility. Verify package dimensions match existing layout constraints. Confirm functional equivalence in bypass mode operation.
