Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component status as the FAN53202UC23X is listed as obsolete and no longer manufactured by onsemi. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compatibility with existing board layouts before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a compact, high-current buck regulator with digital control. The 2.4 MHz frequency allows for smaller passive components. Verify that the input voltage range of 2.5 V to 5.5 V matches the system supply and that the 5 A output capability meets load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TinyBuck family of digitally programmable regulators. It integrates power switches and control logic into a small footprint. The UC23X suffix denotes the specific WLCSP-20 package variant. It is designed for portable applications where size and efficiency are critical.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

As the part is obsolete, identify equivalent synchronous buck regulators from onsemi or other manufacturers. Ensure substitute parts match the 5 A output current, 2.4 MHz frequency, and WLCSP-20 package dimensions for direct replacement.
