LT8301IS5#TRPBF

Overview

The LT8301IS5#TRPBF is a high-voltage, no-optocoupler isolated flyback DC/DC converter from Analog Devices. It integrates a 65V switch and supports input voltages up to 42V. The device utilizes primary-side regulation to eliminate the need for optocouplers and error amplifiers, simplifying design while maintaining tight output voltage tolerance. It operates in a TSOT-23-5 package and is qualified under AEC-Q100 standards for automotive reliability.

Feature Summary

Primary-side regulation eliminates optocouplers and error amplifiers
Integrated 65V power switch handles high-voltage isolation
Supports wide input voltage range up to 42V
Automotive-grade qualification ensures reliability

Applications

Isolated power supplies for industrial systems
Battery chargers requiring galvanic isolation
Medical equipment power stages
Automotive electronics with strict reliability requirements

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm that the IS5 variant meets the required temperature grade for your application environment. Ensure compatibility with the intended transformer design, as primary-side regulation relies on accurate magnetic component characteristics for proper feedback loop stability.

Selection Notes

Select this component when minimizing bill of materials and board space is critical due to the absence of secondary-side feedback components. Consider the TSOT-23-5 package constraints for thermal management. Evaluate if the fixed switching frequency options align with EMI requirements. Verify that the load profile does not exceed the internal switch current limits during transient conditions.

Part Context

This part belongs to the LT8301 family of isolated converters designed for compact, cost-effective power solutions. It shares architectural similarities with other primary-side regulated controllers but distinguishes itself through integrated high-voltage switching capabilities and automotive certification. The series targets applications demanding isolation without the complexity of traditional opto-feedback loops.
