LT8708ILWE-1#PBF

Overview

The LT8708ILWE-1#PBF is an 80V bidirectional buck-boost slave controller from Analog Devices. It operates with a supply voltage range of 2.8V to 80V and supports a switching frequency up to 400 kHz. The device features one output phase with a maximum duty cycle of 80% and can handle output currents up to 15A. It functions within a temperature range of -40°C to +125°C and is housed in an eLQFP-64 surface-mount package.

Feature Summary

• Bidirectional buck-boost topology for flexible power flow control
• Slave controller architecture designed for multi-phase parallel operation
• Wide input voltage compatibility supporting above, below, or equal output scenarios

Applications

• Multi-phase high-current DC/DC conversion systems
• Battery-powered equipment requiring bidirectional energy transfer
• Industrial power supplies utilizing master-slave synchronization

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm the specific ILWE-1 suffix matches design requirements as it denotes a distinct variant. Check current distribution status as Mouser indicates restricted sales. Ensure ESD precautions are observed during handling given moisture sensitivity classification.

Selection Notes

Select this part when designing multi-phase systems requiring synchronized slave control. It complements master controllers to distribute load current efficiently. Verify that the eLQFP-64 package fits the PCB layout constraints. Ensure the application utilizes external MOSFETs compatible with the 15A drive capability and 80V rating.

Part Context

This component belongs to the LT8708 family of high-performance buck-boost switching regulator controllers. It is specifically engineered for applications demanding high efficiency and precise current sharing across multiple phases. The 'slave' designation indicates its role in parallel configurations rather than standalone single-phase use.

Replacement Considerations

LT8708IUHG-1#PBF serves as a pin-compatible alternative in a different package format. Both share the same core functionality and electrical specifications. Verify thermal performance differences between the LQFP and QFN packages before substitution.
