LT8618JDDB#TRPBF

Overview

The LT8618JDDB#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It features a wide input voltage range from 3.4V to 60V and provides a fixed 3.3V output at up to 100mA. The device operates with a programmable switching frequency between 200kHz and 2.2MHz, ensuring high efficiency across various load conditions. It incorporates low quiescent current of 1.7µA for standby applications and includes thermal foldback protection. Packaged in a compact 10-DFN (3x2mm) surface-mount footprint, it supports operation temperatures from -40°C to 125°C.

Feature Summary

Synchronous buck topology with integrated power switches
Wide 60V input voltage capability
Programmable switching frequency for optimization
Thermal foldback current limiting

Applications

Industrial control systems
Automotive electronics
Distributed power architectures
Battery-powered equipment

Procurement Notes

Verify the specific suffix JDDB against official Analog Devices documentation to confirm package type and temperature grade. Ensure the ordering part number matches the required tape and reel configuration. Cross-reference the datasheet revision date to validate parameter accuracy before integration into design specifications.

Selection Notes

Select this component when a 60V input rating is required alongside a fixed 3.3V output. The 100mA output current suits low-power loads. Evaluate the 200kHz to 2.2MHz frequency range against EMI constraints and passive component size requirements. Confirm that the DFN-10 package fits the available PCB area.

Part Context

This part belongs to the LT8618 family of high-efficiency synchronous buck regulators. It shares architectural similarities with other LT86xx series devices but is distinguished by its specific 60V input rating and fixed 3.3V output variant. The JDDB suffix denotes the specific DFN-10 package configuration used for surface-mount assembly.
