FAN48615UC08X

Overview

The FAN48615UC08X is a fixed-output synchronous TinyBoost regulator manufactured by onsemi. It operates with an input voltage range of 2.7 V to 4.5 V and provides a fixed output voltage of 5.25 V. The device supports an output current of 1 A and features a switching frequency of 2.3 MHz. It has a maximum static current of 48 uA and operates within a temperature range of -40°C to +85°C. The component is housed in a 9-pin WLCSP package.

Feature Summary

Synchronous rectification for improved efficiency
Fixed output voltage configuration
Compact WLCSP packaging

Applications

Portable electronic devices
Battery-powered systems
Mobile communication equipment

Procurement Notes

Verify the specific suffix UC08X to confirm the 5.25V fixed output variant. Confirm the WLCSP-9 package type matches your PCB layout requirements. Ensure compatibility with the 2.7V to 4.5V input range for your power supply design. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 5.25V boost is required from a single-cell lithium battery or similar low-voltage source. The synchronous topology is suitable for applications demanding higher efficiency than asynchronous alternatives. The small form factor makes it ideal for space-constrained portable designs where board area is limited.

Part Context

This part belongs to the FAN4861 series of TinyBoost regulators, which are designed for low-power boost applications. The series offers various fixed output voltages to suit different system requirements while maintaining a compact footprint and high efficiency characteristics typical of onsemi's power management solutions.
