LT8302IS8E#WTRPBF

Overview

The LT8302IS8E#WTRPBF is an automotive-grade, no-optocoupler isolated flyback DC/DC converter manufactured by Analog Devices. It operates with an input voltage range of 2.8V to 42V and delivers up to 3.6A output current at a maximum switch voltage of 65V. The device features a minimum switching frequency of 12.7kHz and a typical quiescent current of 380µA. Packaged in an 8-lead SOIC with an exposed pad (SO-8), it supports junction temperatures from -40°C to +125°C and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

Eliminates the need for optocouplers and feedback resistors through integrated primary-side regulation
Supports both positive and negative isolated output configurations via transformer winding polarity selection
Includes internal high-voltage startup circuitry to enable operation from low input voltages

Applications

Automotive infotainment systems requiring isolated power rails
Industrial control interfaces needing galvanic isolation
Battery-powered equipment utilizing primary-side regulation

Procurement Notes

Verify the specific suffix WTRPBF confirms the tape-and-reel packaging format and lead-free status. Confirm that the IS8E designation matches the required industrial temperature grade and SOIC-8 package dimensions. Ensure compatibility with AEC-Q100 requirements if deploying in automotive environments. Cross-reference the manufacturer datasheet for exact pinout and thermal pad specifications.

Selection Notes

Select this component when designing isolated flyback converters that require simplified feedback loops without optocouplers. It is suitable for applications demanding high efficiency at light loads due to low quiescent current. Consider the 65V switch rating and 42V input limit when defining transformer turns ratios. Verify that the 3.6A peak current capability meets the load requirements during transient conditions.

Part Context

This part belongs to the LT8302 family of no-opto isolated flyback controllers. It shares core architecture with variants like the LT8302IS8E#WPBF, differing primarily in packaging and reel configuration. The series is designed to replace traditional optocoupler-based solutions in compact power supplies.
