LT8697EUDD#TRPBF

Special Purpose Regulators Overview

The LT8697EUDD#TRPBF is a high-efficiency, synchronous step-down switching regulator designed for USB power applications. It integrates a 42V input capable switch and delivers up to 2.5A output current at 5V. The device features cable drop compensation to maintain accurate voltage at the load. Operating from an input range of 3.8V to 42V, it supports adjustable switching frequencies up to 2.2MHz. Packaged in a compact 24-lead QFN (3mm x 5mm) footprint, it ensures minimal board space usage while providing robust protection against over-voltage, over-current, and thermal overload conditions.

Special Purpose Regulators Feature Summary

• Integrated cable drop compensation maintains precise output voltage at the load despite cable resistance
• High-speed synchronous buck architecture enables efficient power conversion with minimal external component count
• Wide input voltage range supports direct connection to various bus architectures and battery sources

Special Purpose Regulators Applications

• USB Type-C and legacy USB charging systems requiring precise voltage regulation
• Point-of-load regulation for portable electronics and industrial equipment
• Battery-powered devices needing efficient step-down conversion from higher voltage rails

Special Purpose Regulators Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the EUDD package code corresponds to the 24-lead QFN (3x5mm) variant. Ensure compatibility with Analog Devices DC1396A evaluation board if prototyping. Check for RoHS compliance status as indicated in official documentation. Validate that the part number matches the exact pinout and thermal pad requirements for your PCB layout.

Special Purpose Regulators Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside high efficiency. It is suitable for designs where cable resistance impacts load voltage accuracy due to its built-in compensation feature. Consider the 24-QFN package for space-constrained layouts. Compare against other USB regulators if lower input voltages or different current ratings are sufficient for the application.

Special Purpose Regulators Part Context

This part belongs to the LT8697 family of high-efficiency synchronous buck converters. It shares architectural similarities with the LT8698 but differs in output current capabilities and specific feature sets. The series targets USB power management applications requiring compact solutions. Other variants in the lineup may offer different switching frequencies or integrated FET configurations.

Special Purpose Regulators Replacement Considerations

LT8697EUDD#PBF is the tube-packaged equivalent of the same functional device. LT8698SEV#PBF offers similar USB regulation features but with different current specifications. Verify pin-to-pin compatibility and electrical parameters before substituting with any alternative part numbers.
