LT8301IS5#WTRMPBF

Overview

The LT8301IS5#WTRMPBF is a high-voltage isolated flyback switching regulator from Analog Devices, housed in a TSOT-23-5 package. It supports an input voltage range up to 42V and delivers a regulated output of 65V at 1.2A. The device integrates a primary-side regulation architecture that eliminates the need for optocouplers or auxiliary bias windings. It features AEC-Q100 automotive qualification and operates within a junction temperature range of -40°C to 125°C.

Feature Summary

Primary-side regulation technology removes the requirement for optocouplers and feedback components
Integrated high-voltage switch capable of handling up to 100V drain-source voltage
Automotive-grade reliability with AEC-Q100 certification for harsh environments

Applications

Isolated power supplies for automotive infotainment systems
Battery management system (BMS) auxiliary power generation
Industrial sensor isolation interfaces
Medical equipment isolated channel powering

Procurement Notes

Verify the specific suffix WTRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and moisture sensitivity level. Ensure the component meets AEC-Q100 requirements if deployed in automotive applications. Cross-reference the datasheet for thermal pad soldering guidelines to guarantee reliable surface-mount assembly.

Selection Notes

Select this component when designing compact isolated converters requiring high input voltages without secondary-side feedback loops. The TSOT-23-5 package suits space-constrained layouts. Evaluate thermal performance under maximum load conditions due to the integrated switch dissipation. Confirm compatibility with external transformer specifications for the desired 65V output capability.

Part Context

This part belongs to the LT8301 family of uP No-Opto Iso Fly Converters. It shares architectural similarities with the LT8300 and LT8302 series but offers distinct output current and voltage ratings tailored for specific isolation needs. The family emphasizes simplified design cycles by integrating control logic directly with the power stage.
