LT8708HUHG#TRPBF

Overview

The LT8708HUHG#TRPBF is a high-performance synchronous 4-switch buck-boost DC/DC controller manufactured by Analog Devices. It operates with an input voltage range of 2.8 V to 80 V and supports output voltages from 1.3 V to 80 V. The device features a switching frequency up to 400 kHz and a maximum duty cycle of 80%. It utilizes a 40-pin QFN package (5x8 mm) and functions as a non-isolated regulator. Operating temperatures range from -40°C to +150°C, with rise and fall times of 20 ns.

Feature Summary

• Synchronous four-switch buck-boost topology for efficient voltage conversion
• Wide input and output voltage handling capabilities
• Integrated clock synchronization support

Applications

• Industrial power systems requiring wide input ranges
• Battery-powered equipment with varying charge states
• Automotive electronics operating under fluctuating supply conditions

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 for the Analog Devices component batch.

Selection Notes

Select this controller for applications demanding operation where input voltage exceeds, equals, or falls below the output requirement. The 40-QFN package suits space-constrained designs. Verify thermal management requirements given the 150°C maximum junction temperature rating and exposed pad mounting style.

Part Context

This component belongs to the LT8708 family of buck-boost regulators. It serves as a master controller in multi-phase configurations or standalone solutions. The HUHG suffix denotes the specific temperature grade and package variant within the Analog Devices portfolio.

Replacement Considerations

LT8708HUHG-1#PBF is a documented variant within the same series. Verify pinout compatibility and functional equivalence before substitution.
