LT8618IDDB-3.3#TRMPBF

Overview

The LT8618IDDB-3.3#TRMPBF 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 capable of delivering up to 100mA, operating within an input voltage range of 3.4V to 60V. The device supports adjustable switching frequencies from 200kHz to 2.2MHz and operates over a junction temperature range of -40°C to 125°C. Packaged in a 10-WFDFN with exposed pad (3x2mm), it integrates internal switches and control circuitry for stable DC-DC regulation.

Feature Summary

Synchronous rectification architecture ensures high efficiency across load conditions
Wide 60V input voltage tolerance accommodates various supply sources
Adjustable switching frequency allows optimization for size or noise requirements
Compact 10-pin DFN package minimizes PCB footprint

Applications

Industrial sensor node power supplies
Portable instrumentation systems
Automotive electronics requiring wide input ranges
Battery-powered devices needing efficient step-down regulation

Procurement Notes

Verify the complete part number including suffix #TRMPBF to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status matches project requirements. Check manufacturer datasheet for latest thermal and electrical specifications before finalizing design integration.

Selection Notes

Select this component when a fixed 3.3V output is required with moderate current capability under high input voltages. Consider the 100mA limit for load demands and verify that the 3.4V minimum input aligns with source availability. Evaluate thermal performance based on ambient conditions and PCB copper area for adequate heat dissipation.

Part Context

This part belongs to the LT8618 family of high-voltage synchronous buck regulators from Analog Devices. It shares core topology with variants offering different outputs or packages but is specifically configured for a fixed 3.3V rail. The IDDB designation indicates industrial temperature grade and DFN-10 packaging.
