LT3002IS8E#TRPBF

Overview

The LT3002IS8E#TRPBF is a monolithic micropower isolated flyback converter from Analog Devices. It accepts an input voltage range up to 36V and provides a single adjustable output starting at 1V. The device delivers a maximum output current of 3.6A with a switching frequency of 12kHz. It operates without an optocoupler by sampling the isolated output voltage directly from the primary-side flyback waveform. The component is housed in an 8-SOIC package with an exposed pad and supports junction temperatures from -40°C to 125°C.

Feature Summary

• Eliminates the need for optocouplers and traditional feedback loops by utilizing primary-side sensing of the flyback waveform.
• Provides precise regulation of isolated outputs through direct voltage sampling on the primary side.
• Supports wide input voltage ranges suitable for various industrial and commercial power supply architectures.

Applications

• Isolated DC-DC conversion in industrial control systems
• Power supplies for communication equipment requiring galvanic isolation
• Battery-powered devices needing efficient isolated voltage regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the AEC-Q100 qualification status aligns with automotive or high-reliability requirements if applicable. Ensure the SO-8 package dimensions match the target PCB footprint. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid confusion with similar variants like the #PBF lead-free version.

Selection Notes

Select this component when designing isolated flyback converters that require simplified feedback mechanisms. It is suitable for applications where minimizing component count and board space is critical. Consider the 36V input limit and 3.6A output capability against load requirements. Evaluate thermal performance given the exposed pad design for heat dissipation in the SO-8 package.

Part Context

This part belongs to the LT3002 series of micropower isolated flyback converters. It shares core functionality with other variants such as LT3002IS8E#PBF, differing primarily in packaging format. The series is designed for applications requiring reliable isolated power generation without complex secondary-side control circuitry.

Replacement Considerations

LT3002IS8E#PBF serves as a tube-packaged alternative within the same family. Verify pinout compatibility and electrical specifications before substitution. No other distinct substitute part numbers are publicly confirmed for direct replacement.
