LT8618JDDB#TRMPBF

Overview

The LT8618JDDB#TRMPBF is a high-efficiency, synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range from 3.4V to 60V and provides a fixed 3.3V output at up to 100mA. The device features a programmable switching frequency between 200kHz and 2.2MHz and draws only 1.7µA of quiescent current in standby mode. Packaged in a compact 10-DFN (3x2) surface-mount case, it supports operation over a junction temperature range of -40°C to 125°C.

Feature Summary

Synchronous buck topology for enhanced conversion efficiency
Integrated 60V power switch capability
Ultra-low quiescent current consumption
Programmable switching frequency selection

Applications

Industrial control systems
Automotive electronics
Distributed power architectures

Procurement Notes

Verify the specific suffix JDDB against official Analog Devices documentation to confirm package type and thermal characteristics. Confirm RoHS compliance status via the manufacturer datasheet. Check authorized distributor availability as supply may be limited or subject to factory order constraints.

Selection Notes

Select this component when a fixed 3.3V output is required within a 60V input system. Ensure the load current does not exceed 100mA. Verify that the chosen switching frequency aligns with external component selection and EMI requirements. Compare against adjustable variants if flexible output voltage is needed.

Part Context

This part belongs to the LT8618 family of high-voltage synchronous buck regulators. It shares architectural similarities with other members like the LT8618IDDB but differs in output configuration. The JDDB suffix denotes a specific package variant within the broader LT8618 product line designed for space-constrained applications.
