LTC3718EG#PBF

Special Purpose Regulators Overview

The LTC3718EG#PBF is a single-output DC/DC controller designed for DDR and QDR memory applications. It operates with an input voltage range of 1.5 V to 36 V and provides an adjustable output voltage from 0.75 V to 18 V. The device supports up to 20 A output current and features a switching frequency of 1.4 MHz. It functions within an operating temperature range of -40°C to +85°C and is housed in a 24-SSOP package.

Special Purpose Regulators Feature Summary

• Integrated controller architecture optimized for synchronous buck conversion in memory power supplies
• Wide input voltage capability supporting direct bus or intermediate rail powering
• Adjustable output voltage range suitable for various low-voltage logic standards

Special Purpose Regulators Applications

• DDR memory subsystem power regulation
• QDR memory interface power supply
• General-purpose synchronous step-down control

Special Purpose Regulators Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance status against current Analog Devices RoHS declarations, as legacy documentation may contain conflicting lead content statements. Confirm the SSOP-24 package availability and ensure the design accounts for the extended temperature grade specifications provided in the official datasheet.

Special Purpose Regulators Selection Notes

Select this component when a wide input voltage range up to 36 V is required for driving low-voltage memory loads. The integrated controller approach necessitates external MOSFETs and passive components. Ensure the thermal design accommodates the 24-SSOP package constraints for the target current levels.

Special Purpose Regulators Part Context

This part belongs to the LTC3718 family of high-performance synchronous buck controllers. It is distinct from fixed-output regulators like the LTC3418 series by offering programmable output parameters. The EG#PBF designation specifies the commercial/extended temperature grade and tube packaging format.

Special Purpose Regulators Replacement Considerations

Direct pin-compatible replacements are not explicitly confirmed in public documentation. Evaluate similar Analog Devices memory controllers such as the LTC3714 or LTC3728 families for functional equivalence, verifying input/output ranges and package compatibility.
