Overview
The LT3790HFE#TRPBF is a synchronous four-switch buck-boost voltage and current regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4.7V to 60V and supports output voltages up to 60V. The device regulates output currents up to 10A across two phases. It features a programmable switching frequency between 200kHz and 700kHz, with clock synchronization capability. The component functions within a temperature range of -40°C to +150°C and utilizes a TSSOP-EP-38 package for surface mount installation.
Feature Summary
- Synchronous four-switch buck-boost topology enabling seamless transition between buck and boost modes
- Independent regulation of both output voltage and output current
- Clock synchronization capability for multi-phase or parallel system operation
- Wide operating input voltage range supporting high-voltage applications
Applications
- Industrial power supplies requiring wide input voltage ranges
- Battery-powered systems with varying cell counts
- Automotive electronics operating under fluctuating line conditions
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the HFE variant meets the required thermal performance specifications for the intended application environment. Ensure compatibility with external components such as inductors and capacitors based on the selected switching frequency. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design requirements.
Selection Notes
Select this controller for applications requiring independent voltage and current regulation in a buck-boost configuration. Consider the 60V maximum rating for input and output voltages. Evaluate the need for clock synchronization if multiple units are used in parallel. Verify that the TSSOP-EP-38 package provides adequate thermal dissipation for the expected load current. Compare against the LT3791 series if single-output configurations are sufficient.
Part Context
The LT3790 belongs to Analog Devices' family of synchronous buck-boost controllers designed for high-efficiency power conversion. It complements other variants like the LT3791, which offers single-output capabilities. The device is part of the broader PMIC portfolio aimed at industrial and automotive markets. Development tools such as the DC1666A are available for evaluation purposes.
Replacement Considerations
The LT3790EFE#TRPBF serves as a direct functional substitute within the same product family. Both devices share identical electrical specifications and control logic. Verify package compatibility and thermal performance when substituting. No changes in function are implied by the different suffixes regarding the core controller operation.
