LT8302ES8E-3#TRPBF

Overview

The LT8302ES8E-3#TRPBF is a high voltage isolated flyback switching regulator from Analog Devices. It operates with an input voltage range of 2.8V to 42V and delivers up to 3.6A output current at 65V. The device features ultra-low quiescent current of 380µA and supports switch frequencies down to 12.7kHz. Packaged in an SOIC-8, it provides galvanic isolation without requiring an optocoupler.

Feature Summary

• Eliminates the need for optocouplers and feedback windings through integrated primary-side regulation
• Provides precise secondary-side voltage regulation via internal sense resistor monitoring
• Supports flexible operation with adjustable switching frequency and programmable soft-start

Applications

• Industrial power supplies requiring galvanic isolation
• Battery chargers for portable equipment
• Telecommunications infrastructure power systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the ES grade meets your thermal requirements compared to IS or HS variants. Ensure compatibility with your PCB footprint for the SOIC-8 package before finalizing procurement orders.

Selection Notes

Select this component for designs prioritizing minimal external component count and high efficiency at low switching frequencies. Consider the thermal dissipation capabilities of the SOIC-8 package relative to your expected load conditions and ambient temperature constraints.

Part Context

This part belongs to the LT8302 family of isolated flyback converters designed for applications demanding high reliability and reduced bill-of-materials complexity. It integrates the controller, driver, and high-voltage switch into a single compact solution.

Replacement Considerations

LT8302IS8E-3#PBF offers identical electrical performance in tube packaging. LT8302HS8E#WTRPBF provides extended temperature range support while maintaining the same functional specifications and pinout configuration.
