Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as this component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm that the specific suffix MP18X matches the required fixed 1.8V output voltage and 6-MLP package type. Ensure compatibility with the target PCB footprint and thermal requirements for the MLP-6 form factor.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 1.8V rail is required for low-power digital loads. The fixed output eliminates external resistor programming. Consider the 300mA limit against peak load demands. The synchronous design offers better performance than non-synchronous alternatives at similar current levels within the specified input voltage window.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the FAN5307 series of step-down converters. It shares the core topology and control architecture with other variants in the family, such as adjustable versions or those with different output voltages. The primary distinction lies in the internal feedback network setting the 1.8V level and the specific MLP-6 package designation.
