Overview
The LT8390JFE#TRPBF is a synchronous four-switch buck-boost DC/DC controller from Analog Devices, designed for wide input voltage ranges. It supports an input voltage range of 4V to 60V and delivers regulated outputs up to 60V. The device operates with a switching frequency between 150kHz and 650kHz, featuring integrated soft start functionality. Packaged in a TSSOP-28 form factor, it includes protection features such as current limit and shutdown control. The component is suitable for applications requiring efficient power conversion across varying source conditions.
Feature Summary
- Synchronous four-switch topology enabling efficient buck and boost operation
- Integrated soft start function to manage inrush current during startup
- Supports clock synchronization for noise reduction in multi-phase systems
Applications
- Industrial automation power supplies
- Battery-powered equipment with variable source voltages
- Distributed power systems requiring wide input range
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records. Check for any recent product change notifications that may affect specifications or availability. Validate that the component matches the exact part number to avoid pinout mismatches.
Selection Notes
Select this controller when a wide input voltage range from 4V to 60V is required. Consider the 150kHz to 650kHz switching frequency range for balancing efficiency and component size. Evaluate the TSSOP-28 package constraints against thermal requirements. Compare against other LT8390 variants if different frequency ranges or packaging options are needed. Ensure the application benefits from the integrated soft start feature.
Part Context
This component belongs to the LT8390 family of synchronous buck-boost controllers. It shares architectural similarities with other parts in the series but differs in specific electrical parameters and packaging. The JFE variant specifically denotes the temperature grade and package type. Development kits like DC2457A are available for evaluating performance characteristics.
Replacement Considerations
LT8390JFE#PBF offers identical electrical specifications in tube packaging instead of tape and reel. LT8390IFE#TRPBF provides similar functionality with potential differences in operating temperature range or package lead style. Verify pin compatibility and thermal performance before substituting.
