LT8618JDDB-3.3#TRMPBF

Overview

The LT8618JDDB-3.3#TRMPBF is a synchronous step-down DC/DC converter manufactured by Analog Devices Inc., housed in a 10-WFDFN package with exposed pad. It provides a fixed output voltage of 3.3V at a maximum current of 100mA. The device supports an input voltage range from 3.4V to 60V and operates with a programmable switching frequency between 200kHz and 2.2MHz. Quiescent current is specified at 1.7µA, and the junction temperature range extends from -40°C to 125°C.

Feature Summary

Synchronous rectification architecture for enhanced efficiency
Programmable switching frequency capability
Low quiescent current operation

Applications

Industrial control systems
Infra-red (IR) cameras
Portable instrumentation

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the specific suffix matches the required fixed output configuration. Review the official datasheet for RoHS compliance status and handling instructions. Ensure supply chain documentation aligns with current manufacturing standards before integration into production designs.

Selection Notes

Select this part when a fixed 3.3V rail is required within a high-voltage input system up to 60V. The 100mA output limit suits low-power applications. Consider the DFN package size for space-constrained layouts. Evaluate thermal performance requirements against the 125°C junction rating during initial design phases.

Part Context

This component belongs to the LT8618 family of high-efficiency synchronous buck converters. It shares core topology and pinout compatibility with other variants in the series, such as adjustable versions or different output configurations. The JDDB suffix indicates the specific fixed-output variant within this product line.
