Overview
The LT8301IS5#WTRPBF is a high voltage, no-optocoupler isolated flyback DC/DC converter manufactured by Analog Devices. It operates with an input voltage range up to 42V and provides a regulated output of 65V at 1.2A. The device integrates the switch and controller in a compact TSOT-23-5 package. It features AEC-Q100 qualification for automotive reliability and supports surface mount installation.
Feature Summary
- Eliminates optocouplers using primary-side regulation for simplified design
- Integrates high-voltage switching transistor within the IC
- Supports isolated positive or negative output configurations
- Qualified for automotive applications under AEC-Q100 standards
Applications
- Automotive power supply systems requiring isolation
- Industrial control circuits needing compact isolated DC/DC conversion
- Battery-powered equipment with high-voltage isolated outputs
Procurement Notes
Verify the specific suffix WTRPBF confirms the reel packaging format and lead-free status. Confirm AEC-Q100 automotive qualification requirements match your system specifications. Ensure the TSOT-23-5 thermal performance meets your application's heat dissipation needs. Check current availability status as distribution may be limited.
Selection Notes
Select this component when a compact, isolated flyback solution is required without optocoupler complexity. It is suitable for applications demanding high input voltages up to 42V and regulated outputs up to 65V. Consider the TSOT-23-5 package constraints for thermal management and PCB space. Verify that the 1.2A output current capability aligns with load requirements.
Part Context
This part belongs to the LT8301 family of no-opto isolated flyback converters. It shares architectural similarities with the LT8300 and LT8302 but differs in output current ratings and package options. The IS5 designation indicates the industrial temperature grade and TSOT-23-5 package variant within the broader product line.
Replacement Considerations
LT8300IS5#WTRPBF offers similar functionality with different current ratings. LT8302 variants provide higher output current capabilities in larger packages. Verify pin compatibility and electrical parameters before substitution.
