LT8618IDDB#TRMPBF

Overview

The LT8618IDDB#TRMPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.4V to 60V and provides a fixed 3.3V output at up to 100mA. The device features a programmable switching frequency from 200kHz to 2.2MHz and includes integrated power MOSFETs. It is housed in a 10-WFDFN package with exposed pad, rated for junction temperatures between -40°C and 125°C.

Feature Summary

Integrated synchronous rectification for high efficiency
Wide 60V input voltage capability
Programmable switching frequency for optimization
Compact DFN package design

Applications

Industrial control systems
Automotive electronics
Distributed power architectures

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm the IDDB variant corresponds to the fixed 3.3V output configuration. Ensure compatibility with the required thermal management for the 10-DFN package. Check current availability status as supply may be restricted.

Selection Notes

Select this component for applications requiring a wide input voltage range up to 60V with low output current needs. The fixed 3.3V output eliminates external resistor networks. Consider the 100mA limit against load requirements. The synchronous topology offers better efficiency than non-synchronous alternatives at light loads.

Part Context

This part belongs to the LT8618 family of high-efficiency, wide-input voltage synchronous buck regulators. It shares architectural similarities with other members like the LT8618EDB (adjustable) but differs in output configuration. The series targets compact power solutions in industrial and automotive sectors.

Replacement Considerations

LT8618EDB#TRMPBF offers adjustable output instead of fixed 3.3V. LT8619IDD#TRMPBF provides higher current capacity (1.2A). Verify pinout and thermal performance before substitution.
