FAN4860UC5X

Overview

The FAN4860UC5X is a synchronous boost regulator from the TinyBoost series, manufactured by onsemi. It operates with an input voltage range of 2.3 V to 4.5 V and provides a fixed 5 V output at up to 300 mA. The device features a 3 MHz switching frequency and low quiescent current of 45 uA. Packaged in a compact WLCSP-6 format, it supports operation between -40°C and +85°C.

Feature Summary

Synchronous boost topology for high efficiency
TinyBoost package for space-constrained designs
Fixed 5V output capability

Applications

USB OTG communication lines
HDMI communication lines
Smartphone power systems
Portable media players

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Review datasheet revisions for any parameter updates prior to final design integration.

Selection Notes

Select this component for applications requiring a fixed 5V rail from single-cell lithium sources. The 3MHz frequency allows smaller passive components compared to lower-frequency alternatives. Ensure input voltage remains within the 2.3V minimum threshold for proper regulation.

Part Context

Part of the Fairchild/Onsemi TinyBoost family designed for portable electronics. Replaced legacy linear regulators in USB/HDMI power paths. Manufactured under onsemi brand following acquisition.
