Overview
The FAN48617UC50X is a synchronous TinyBoost regulator manufactured by onsemi, designed for efficient DC-DC power conversion. It operates with an input voltage range of 2.7 V to 4.5 V and provides a fixed 5 V output at up to 1 A load current. The device features a 2.3 MHz switching frequency and low quiescent current of 45 uA. Packaged in a compact 9-WLCSP (1.78x1.78 mm) format, it supports surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Synchronous rectification architecture for enhanced efficiency
- Fixed 5 V output configuration simplifies design integration
- Compact WLCSP package minimizes board space requirements
Applications
- Portable electronic devices requiring efficient step-up conversion
- Battery-powered systems needing stable 5 V rails
- Space-constrained consumer electronics
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and check for specific EOL notices or PCN updates prior to final procurement decisions. Ensure supply chain documentation matches the exact part number suffix UC50X.
Selection Notes
Select this component when a fixed 5 V output is required from a single-cell lithium battery source. The synchronous topology offers better efficiency than asynchronous alternatives at moderate loads. The small WLCSP footprint makes it suitable for dense PCB layouts where traditional SOT packages are too large.
Part Context
This part belongs to onsemi's TinyBoost family of synchronous boost regulators. These ICs are engineered for portable applications requiring high efficiency in minimal footprints. The FAN48617 variant specifically targets fixed-output applications, distinguishing it from programmable counterparts in the same series.
Replacement Considerations
Direct substitutes include FAN48619UC50X and FAN48630UC50X. Verify pin compatibility and electrical specifications before substitution. Note that FAN48630 offers higher current capability while FAN48619 shares similar fixed-output characteristics.
