FAN49100AUC360X

Overview

The FAN49100AUC360X is a TinyPower synchronous buck-boost switching regulator manufactured by onsemi. It operates within an input voltage range of 2.5 V to 5.5 V and provides a fixed output voltage of 3.6 V. The device supports an output current of 2.5 A with a switching frequency of 1.8 MHz. Quiescent current is specified at 27 uA. It features a shutdown function and operates across a temperature range of -40°C to +85°C. The component is housed in a WLCSP-20 package.

Feature Summary

• Synchronous buck-boost topology for flexible power conversion
• Integrated shutdown control for power management
• Compact WLCSP-20 footprint for space-constrained designs

Applications

• Portable battery-powered electronics
• Industrial sensor nodes
• IoT communication modules

Procurement Notes

Verify the specific suffix '360' confirms the 3.6 V fixed output configuration. Confirm the WLCSP-20 package type matches the target PCB layout. Check RoHS compliance status as indicated in official documentation. Ensure the operating temperature range meets system requirements. Validate that the shutdown pin functionality aligns with the application logic.

Selection Notes

Select this part when a fixed 3.6 V output is required from a single-cell lithium-ion or similar battery source. The 2.5 A output capability suits moderate load applications. The 1.8 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the WLCSP-20 package constraints during mechanical design.

Part Context

This component belongs to the TinyPower series, designed for high efficiency in small form factors. It complements other variants like the FAN49100AUC330X which offers different output voltages. The series targets applications requiring robust performance in compact portable devices.

Replacement Considerations

FAN49100AUC330X offers a 3.3 V output instead of 3.6 V. Verify if the voltage difference impacts the downstream circuitry before substitution.
