Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring efficient step-down regulation
• Mobile devices utilizing low-voltage core power supplies
• Embedded systems needing compact DC-DC conversion solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or onsemi, as corporate acquisitions may affect labeling. Confirm the specific suffix 'AUC08X' corresponds to the 0.8V fixed output variant. Ensure the package type matches the required 6-UFBGA WLCSP form factor for PCB layout compatibility. Check RoHS compliance status if environmental regulations apply to your assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 0.8V output is required rather than an adjustable range. The 6MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 600mA to 750mA output current limit against your load requirements. The synchronous design is preferable for applications prioritizing thermal performance and efficiency over cost-sensitive non-synchronous options.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN53612 series of TinyBuck regulators designed for high-density power applications. The series typically offers various output voltage options and current ratings within the same footprint family. The FAN53612AUC08X specifically targets applications demanding precise low-voltage regulation in minimal board space.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official cross-reference lists for direct pin-compatible substitutes within the FAN53612 family. Verify that any alternative maintains the 0.8V fixed output and similar current capabilities. Ensure the replacement supports the same WLCSP6 package dimensions for mechanical interchangeability.
