LT8301JS5#WTRMPBF

Overview

The LT8301JS5#WTRMPBF is an automotive-grade, no-optocoupler isolated flyback converter from Analog Devices. It supports input voltages up to 42V and delivers a regulated output with high isolation capabilities. The device integrates a 65V switch and features a 1.2A current limit for robust operation in compact designs. Packaged in a TSOT-23-5 surface-mount case, it ensures reliable performance across the specified temperature range while maintaining high efficiency without external feedback components.

Feature Summary

Eliminates optocouplers by utilizing primary-side regulation for precise output control
Integrates a 65V power switch to simplify circuit design and reduce component count
Supports wide input voltage ranges suitable for various industrial and automotive applications

Applications

Automotive infotainment systems requiring isolated power rails
Industrial sensor interfaces needing galvanic isolation
Medical equipment with strict safety isolation requirements

Procurement Notes

Verify the specific suffix WTRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and automotive qualification status. Ensure compatibility with your manufacturing process regarding moisture sensitivity levels. Cross-reference the full part number with authorized distributors to confirm current availability and authenticity before procurement.

Selection Notes

Select this component when designing isolated flyback converters that require high reliability in automotive environments. It is suitable for applications demanding minimal bill-of-materials due to the absence of optocouplers. Consider the thermal performance within the TSOT-23-5 package and ensure the input voltage does not exceed the 42V maximum rating for safe operation.

Part Context

This part belongs to the LT8301 family of no-opto isolated flyback converters. It shares architectural similarities with other members like the LT8300 and LT8302 but differs in package type and specific electrical ratings. The JS5 designation indicates an automotive-grade variant optimized for harsh operating conditions compared to standard commercial versions.
