LT8301JS5#TRPBF

Overview

The LT8301JS5#TRPBF is a high-efficiency, isolated flyback converter from Analog Devices. It integrates a 65V MOSFET and supports input voltages up to 42V. The device features an ultra-low quiescent current of 1.2µA in standby mode. It operates without an optocoupler by utilizing primary-side regulation for precise output voltage control. The component is housed in a compact TSOT-23-5 package and meets AEC-Q100 automotive qualification standards.

Feature Summary

Integrated 65V power switch eliminates external high-voltage components
Primary-side regulation removes the need for optocouplers and feedback resistors
Ultra-low standby current enables efficient battery-powered operation
Automotive-grade reliability with AEC-Q100 certification

Applications

Battery-operated portable medical devices
Industrial sensor nodes requiring isolation
Low-power consumer electronics with strict standby limits
Automotive infotainment and instrumentation systems

Procurement Notes

Verify the specific suffix #TRPBF against the manufacturer's official datasheet to confirm tape-and-reel packaging and temperature grade. Ensure the ordering part number matches the exact electrical specifications required for your design. Cross-reference the component marking code on the physical device with the datasheet documentation to prevent counterfeit substitution. Confirm that the supplier provides valid traceability documents for automotive-grade parts.

Selection Notes

Select this component when designing isolated power supplies where board space is limited and efficiency at light loads is critical. The integrated MOSFET simplifies layout compared to discrete solutions. Primary-side regulation reduces bill-of-materials count by removing optocouplers. Verify that the transformer design aligns with the controller's switching frequency and duty cycle limits for optimal performance.

Part Context

This part belongs to the LT8301 family of no-opto isolated flyback converters. It shares architectural similarities with the LT8300 but offers higher input voltage tolerance and automotive qualification. The TSOT-23-5 package distinguishes it from larger SOIC or DFN variants within the broader power management portfolio.
