LT8302HS8E#PBF

Overview

The LT8302HS8E#PBF is a monolithic isolated flyback converter from Analog Devices, designed for high-voltage applications. It operates with an input voltage range of 3V to 42V and delivers up to 3.6A switch current. The device supports output voltages up to 65V and features a low quiescent current of 380uA. It utilizes a proprietary no-optocoupler control scheme for isolation feedback. The component is housed in an 8-SOIC package with an exposed pad (SOIC-EP) and is qualified to AEC-Q100 standards for automotive use. It functions within a temperature range of -40°C to +150°C TJ.

Feature Summary

Integrated no-optocoupler isolated flyback controller for simplified design
AEC-Q100 qualified for automotive reliability requirements
High input voltage capability up to 42V with 3.6A switch current
Low quiescent current operation for improved efficiency

Applications

Automotive battery management systems
Industrial isolated power supplies
Medical equipment requiring galvanic isolation
Distributed power architectures

Procurement Notes

Verify the specific suffix 'HS' indicates the extended temperature grade and automotive qualification status. Confirm the package marking matches the SOIC-8 EP specification. Ensure compatibility with the required thermal dissipation capabilities given the exposed pad design. Check for any specific handling instructions related to moisture sensitivity level as indicated in the datasheet.

Selection Notes

Select this part when high input voltages up to 42V are required alongside strict automotive qualification standards. The no-optocoupler feature reduces component count and improves long-term reliability compared to traditional opto-isolated designs. Consider the 3.6A switch current limit when sizing external magnetics. The exposed pad package requires careful PCB thermal design to manage junction temperatures effectively under load.

Part Context

This component belongs to the LT8302 family of isolated flyback converters. Unlike standard industrial versions, the HS suffix denotes automotive-grade qualification and extended temperature performance. It shares architectural similarities with other members like the IS8E variants but differs in reliability testing and operating temperature ranges. The family focuses on eliminating optocouplers while maintaining precise regulation across wide input variations.
