Special Purpose Regulators Procurement Notes

Verify the manufacturer designation, as Fairchild Semiconductor was acquired by onsemi. Confirm the specific suffix 'MTCX' corresponds to the 24-pin TSSOP package and tape-and-reel packaging format. Ensure the component meets the required operating temperature range of 0°C to 70°C for your specific application environment.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for AMD Hammer processors or similar high-current logic loads requiring two-phase interleaving. The fixed input range of 10.8V–13.2V suits standard server or workstation power rails. Consider the thermal performance of the 24-pin TSSOP package relative to the expected load current and ambient conditions.

Special Purpose Regulators Part Context

This part belongs to the FAN5098 series of synchronous buck controllers. It is specifically engineered to meet the transient response and efficiency requirements of advanced microprocessors. The technology leverages synchronous rectification to minimize conduction losses compared to traditional diode-based solutions.

Special Purpose Regulators Replacement Considerations

Check for direct pin-compatible alternatives from onsemi or other manufacturers offering similar two-phase synchronous buck controllers. Verify that any substitute supports the same input voltage window and output voltage programming range.
