LT8697HUDD#PBF

Special Purpose Regulators Overview

The LT8697HUDD#PBF is a synchronous step-down switching regulator designed for USB charging applications. It integrates a 42V input range and delivers up to 2.5A output current at 5V. The device features cable compensation to maintain accurate output voltage despite line drops. It operates with a fixed switching frequency and includes integrated soft-start functionality.

Special Purpose Regulators Feature Summary

• Integrated cable compensation for precise load regulation
• Synchronous buck topology for high efficiency
• Wide 42V input voltage capability
• Built-in soft-start mechanism

Special Purpose Regulators Applications

• USB charger systems
• Industrial power supplies
• Distributed power architectures

Special Purpose Regulators Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with required thermal management solutions given the exposed pad package. Confirm availability status as supply conditions may vary by region.

Special Purpose Regulators Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside high output current. The integrated cable compensation feature makes it suitable for applications where long wire runs cause significant voltage drop. Consider thermal performance requirements due to the power density of the design.

Special Purpose Regulators Part Context

This part belongs to the LT869x family of synchronous buck regulators from Analog Devices. It shares architectural similarities with other members like the LT8698, differing primarily in output current ratings and specific integration features tailored for USB standards.

Special Purpose Regulators Replacement Considerations

Direct substitutes include the LT8698 series variants. Verify that alternative parts support the same 42V input rating and sufficient output current for the specific application load requirements.
