FAN48630UC315X

Overview

The FAN48630UC315X is a synchronous TinyBoost regulator manufactured by onsemi, designed for single-cell lithium-ion battery applications. It operates within an input voltage range of 2.35 V to 5.5 V and provides fixed output voltages of 3.15 V or 3.33 V. The device supports a continuous output current of 1.5 A with a switching frequency of 2.5 MHz. Key electrical specifications include a maximum quiescent current of 55 uA and a shutdown supply current of 150 uA. It functions reliably across an operating temperature range from -40°C to +85°C and utilizes a 16-WLCSP package.

Feature Summary

• Integrates a bypass mode to allow direct power delivery when the input voltage exceeds the regulated output level, enhancing system efficiency.
• Features synchronous rectification to maximize conversion efficiency and minimize heat generation during high-current operation.
• Includes a dedicated shutdown pin to significantly reduce standby power consumption in portable devices.

Applications

• Single-cell lithium-ion battery powered portable electronics
• Mobile communication devices requiring efficient step-up regulation
• Battery-operated consumer gadgets needing compact power management solutions

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm package integrity upon receipt as WLCSP components are sensitive to mechanical stress. Ensure compatibility with existing PCB footprint designs before integration. Review latest datasheet revisions for any updated handling or testing procedures.

Selection Notes

Select this component for designs requiring a compact solution for boosting single-cell Li-Ion battery voltage. The fixed 3.15 V/3.33 V output eliminates external resistor networks. Consider the 2.5 MHz frequency for balancing component size and efficiency. Verify that the 1.5 A current rating meets peak load requirements of the target application.

Part Context

This part belongs to the FAN48630 series of synchronous boost regulators. It shares architectural similarities with other models in the family but differs in fixed output voltage configuration. The series is characterized by its small form factor and integrated bypass functionality, targeting space-constrained mobile applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life (EOL) status indicated in source materials, alternative sourcing should be managed through authorized lifecycle management channels or verified equivalent parts from the manufacturer's current portfolio.
