Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'AUC13X' against official datasheets to confirm the fixed 1.3 V output voltage. Confirm RoHS compliance status through manufacturer documentation. Check for End-of-Life (EOL) notices as availability may be restricted. Ensure the WLCSP-6 package dimensions match the target PCB footprint requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.3 V rail is required from a 2.3 V to 5.5 V source. The 6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 1 A load current requirement does not exceed thermal limits in the intended application environment. Consider the WLCSP-6 package size constraints during layout design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN53611 series of TinyBuck regulators. It shares architectural similarities with other variants like FAN53611AUC12X but differs in the fixed output voltage setting. The series is designed for space-constrained applications requiring high efficiency and fast transient response.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

FAN53611AUC12X offers a similar 1 A synchronous buck profile but provides a fixed 1.2 V output instead of 1.3 V. Verify if the voltage difference is acceptable for the downstream circuitry before substituting.
