LT8708HUHG#PBF

DC DC Switching Controllers Overview

The LT8708HUHG#PBF is an 80V synchronous four-switch buck-boost DC/DC controller from Analog Devices. It supports bidirectional power flow and operates with input voltages above, below, or equal to the output voltage. The device features a wide VIN range of 2.8V to 80V (requiring EXTVCC > 6.4V) and a VOUT range of 1.3V to 80V. It offers six independent regulation modes for VIN/VOUT and current control. The component utilizes a 40-pin QFN package (5mm x 8mm) and is rated for operation between -40°C and +150°C.

DC DC Switching Controllers Feature Summary

Supports true bidirectional power transfer for energy regeneration and charging
Enables single-inductor design with flexible voltage relationships
Provides six independent regulation modes for precise system control

DC DC Switching Controllers Applications

Automotive 48V systems
Bidirectional charging systems
High-voltage buck-boost converters
Humanoid robot dual battery storage

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF against official Analog Devices documentation to confirm tape-and-reel packaging and standard lead-free compliance. Ensure that the HUHG designation matches the required high-temperature industrial rating of up to 150°C for your application environment. Cross-reference the AEC-Q100 certification status if automotive qualification is mandatory for the final product deployment.

DC DC Switching Controllers Selection Notes

Select this controller when input and output voltages may cross each other during operation. The device is suitable for applications requiring simultaneous regulation of multiple parameters such as input voltage, output voltage, and currents in both directions. Consider the 40-pin QFN footprint and thermal requirements when designing the PCB layout for optimal heat dissipation.

DC DC Switching Controllers Part Context

This component belongs to the LT8708 series of high-performance buck-boost switching regulator controllers. The HUHG variant specifically denotes the high-temperature industrial grade version within the family. It shares core architectural features with the EUHG and IUHG models but differs in its extended operating temperature range suitable for harsh environments.
