LT8331IMSE#WTRPBF

Overview

The LT8331IMSE#WTRPBF is an automotive-grade DC-DC switching regulator from Analog Devices Inc., housed in a 16-MSOP-EP package. It supports Boost, Flyback, SEPIC, and Inverting topologies with adjustable output voltages ranging from 1.6V to 140V (switch) and -0.8V for negative outputs. The device accepts input voltages between 4.5V and 100V, delivering up to 500mA switch current. Operating frequencies range from 100kHz to 500kHz, with a junction temperature range of -40°C to 125°C.

Feature Summary

Automotive-grade qualification ensuring reliability under harsh environmental conditions
Integrated high-voltage power switch capable of handling up to 140V
Flexible topology support including boost, flyback, SEPIC, and inverting configurations
Low quiescent current operation for enhanced energy efficiency

Applications

Automotive infotainment systems
Medical equipment power supplies
Industrial sensor interfaces
Battery-powered portable devices

Procurement Notes

Verify the suffix WTRPBF confirms tape-and-reel packaging and automotive grade status. Ensure the order matches the specific MSOP-EP package requirements. Confirm RoHS compliance and material declarations align with project specifications before finalizing procurement.

Selection Notes

Select this component when high input voltage tolerance and flexible topology options are required for automotive or industrial applications. Consider the 500mA switch current limit and 100V maximum input voltage against load requirements. Evaluate thermal performance within the specified junction temperature range for optimal reliability.

Part Context

This part belongs to the LT8331 family of low IQ converters. It shares functional similarities with LT8331EMSE#PBF but differs in packaging format and automotive qualification. The IMSE variant specifically targets rugged environments requiring AEC-Q100 certification.
