LT8618IDDB-3.3#TRPBF

Overview

The LT8618IDDB-3.3#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact spaces. It features a fixed 3.3V output with a maximum current capacity of 100mA, operating within an input voltage range of 3.4V to 60V. The device supports adjustable switching frequencies between 200kHz and 2.2MHz, allowing optimization for size and efficiency. Packaged in a 10-WFDFN (3x2) exposed pad surface-mount package, it operates reliably across a junction temperature range of -40°C to 125°C.

Feature Summary

Integrated synchronous rectification for enhanced conversion efficiency
Wide input voltage tolerance supporting up to 60V sources
Adjustable switching frequency for flexible design optimization
Compact footprint suitable for space-constrained applications

Applications

Industrial control systems requiring isolated or non-isolated DC-DC conversion
Automotive electronics operating within wide voltage ranges
Portable equipment powered by battery or adapter sources
Distributed power architectures in communication infrastructure

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with RoHS3 standards and check for any recent lifecycle status updates. Cross-reference the DFN-10 package dimensions with your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 3.3V output is required from higher voltage rails up to 60V. Consider the 100mA load capability and the need for external compensation components based on the chosen switching frequency. Evaluate thermal performance requirements given the small DFN-10 package and exposed pad design for heat dissipation.

Part Context

This part belongs to the LT8618 family of high-voltage synchronous buck regulators. It shares core architecture with variants like the LT8618EDDB-3.3#TRMPBF but differs in packaging and reel specifications. The IDDB suffix indicates the specific industrial grade and DFN-10 package type used in this configuration.
