LT8302IS8E#TRPBF

Overview

The LT8302IS8E#TRPBF is a high-voltage isolated flyback DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.8 V to 42 V and delivers up to 3.6 A of output current at voltages up to 65 V. The device features a low quiescent current of 380 uA and supports switching frequencies down to 12.7 kHz. It is qualified under the AEC-Q100 standard for automotive applications and is housed in an SOIC-8 package with an exposed pad.

Feature Summary

• Provides galvanic isolation without requiring an optocoupler or feedback winding
• Supports negative, positive, or multiple isolated outputs from a single transformer
• Capable of operating at very low switching frequencies to minimize magnetics size

Applications

• Automotive power systems requiring isolated rails
• Industrial control systems needing isolated DC/DC conversion
• Medical equipment utilizing isolated power supplies

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and reel specifications. Ensure the component meets AEC-Q100 requirements if used in automotive designs. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when designing isolated power supplies that require high input voltages up to 42 V. It is suitable for applications demanding reduced bill-of-materials by eliminating optocouplers. Consider the thermal performance of the SOIC-8 package with exposed pad for heat dissipation needs.
