Special Purpose Regulators Applications

• Intel processor core voltage regulation
• Single-phase wide VIN range DC/DC conversion systems
• High-current point-of-load power management

Special Purpose Regulators Procurement Notes

Verify the specific suffix and package type against the official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and manufacturing origin through authorized channels. Check for any product change notifications that may affect pinout or electrical characteristics before finalizing procurement orders.

Special Purpose Regulators Selection Notes

Select this component when a single-phase solution is sufficient for loads up to 25 A. Ensure the application requires the specified 4.5 V to 36 V input range. Consider thermal management strategies due to the high current capability in the TSSOP-EP-38 package. Verify that the target processor voltage profile falls within the 0 V to 1.5 V output range.

Special Purpose Regulators Part Context

This part belongs to the LTC3816 series of synchronous step-down controllers. It is distinct from integrated regulators as it controls external MOSFETs. The IFE suffix indicates the industrial temperature grade and TSSOP-EP-38 package variant. It serves as a dedicated controller rather than a complete power stage module.
