FAN5362UC29X

Voltage Regulators - DC DC Switching Regulators Overview

The FAN5362UC29X is a synchronous buck regulator from onsemi, designed for step-down DC-DC conversion. It operates with an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 2.9 V. The device supports a maximum output current of 500 mA or 750 mA, depending on thermal conditions. It integrates a high-frequency switching architecture operating at 3 MHz to minimize external component size. The IC is housed in a compact 6-pin WLCSP package measuring 1.23 mm by 0.88 mm, suitable for space-constrained portable applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Synchronous rectification architecture for improved efficiency
• High-frequency 3 MHz switching operation reduces passive component footprint
• Compact 6-pin WLCSP packaging for minimal board area utilization

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring efficient power management
• Battery-powered devices needing stable low-voltage regulation
• Space-constrained mobile hardware designs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix UC29X confirms the 2.9 V fixed output variant. Confirm the 6-pin WLCSP package dimensions match your PCB layout constraints. Ensure thermal design accounts for the 500 mA/750 mA current ratings under expected load conditions. Check for obsolescence notices as power management ICs may have lifecycle changes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.9 V output is required from a 2.7 V to 5.5 V input source. The 3 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Consider the WLCSP form factor if board real estate is limited. Verify that the 500 mA/750 mA current capability meets the system's peak load requirements without excessive thermal dissipation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN5362 series of synchronous buck regulators. The series focuses on high-efficiency power conversion for portable applications. The UC29X designation specifically indicates the 2.9 V output version within the family. Other variants in the series offer different fixed output voltages or adjustable configurations.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other FAN5362 variants with different output voltages if the voltage requirement changes. Cross-reference with similar 3 MHz synchronous buck regulators from onsemi or other manufacturers offering comparable current ratings and WLCSP packages.
