Overview
The LT8301IS5#TRMPBF is a high-voltage isolated flyback converter from Analog Devices, housed in a TSOT-23-5 package. It supports input voltages up to 42V and integrates a 65V/1.2A switch. The device operates without an optocoupler, utilizing primary-side regulation for cost-effective isolation. It features AEC-Q100 qualification for automotive reliability and offers flexible output configurations with positive or negative voltage options.
Feature Summary
- Eliminates the need for optocouplers through integrated primary-side regulation architecture
- Provides galvanic isolation with flexible positive or negative output polarity options
- Includes an integrated high-voltage power switch rated at 65V and 1.2A
- Meets AEC-Q100 automotive grade standards for enhanced reliability
Applications
- Automotive isolated power supplies
- Battery-powered systems requiring isolation
- Industrial control circuits with isolated outputs
- Medical equipment power stages
Procurement Notes
Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and temperature range. Ensure the component matches the required automotive qualification status. Cross-reference the datasheet for exact pinout compatibility before integration into the design.
Selection Notes
Select this component when a compact isolated solution is required without optocouplers. The TSOT-23-5 package suits space-constrained designs. Verify that the 42V input limit and 1.2A switch current meet the application's power requirements. Confirm AEC-Q100 compliance is necessary for the target market.
Part Context
This part belongs to the LT8301 family of no-opto isolated flyback converters. It shares architectural similarities with other members like the LT8300 but differs in input voltage ratings and switch capabilities. The series targets applications needing efficient, low-component-count isolation.
Replacement Considerations
LT8300IS5#WTRPBF: Similar topology but different input voltage range (up to 100V) and lower switch current (260mA). LT8303IS5#TRMPBF: Adjustable output variant with higher switch current (450mA) but similar package.
