LT8705AEFE#PBF

Overview

The LT8705AEFE#PBF is a synchronous 4-switch buck-boost DC/DC controller from Analog Devices Inc. It supports input and output voltages up to 80V, with an operating range of 2.8V to 80V for Vcc/Vdd. The switching frequency is adjustable between 100kHz and 400kHz. It features two outputs in a 38-TSSOP-EP package, designed for applications requiring operation above, below, or equal to the output voltage.

Feature Summary

Synchronous 4-switch buck-boost topology for efficient power conversion
Supports input voltages above, below, or equal to the output voltage
Integrated clock synchronization capability
Includes control features such as enable, frequency control, and soft start

Applications

Telecom voltage stabilizers
Industrial power supplies
Automotive electronics systems

Procurement Notes

Verify the exact part number LT8705AEFE#PBF against official Analog Devices documentation to ensure compatibility with your design requirements. Confirm that the 38-TSSOP-EP package and lead-free (#PBF) specification meet your assembly constraints. Check for any recent Product Change Notices regarding material or process updates before finalizing procurement.

Selection Notes

Select this component when a wide input voltage range relative to the output is required, specifically where VIN can be higher, lower, or equal to VOUT. Ensure the application demands a synchronous rectified solution for improved efficiency. Verify that the 80V maximum rating aligns with system transient conditions and that the 100kHz to 400kHz frequency range fits EMI and size constraints.

Part Context

The LT8705A is part of Analog Devices' high-performance buck-boost controller family. It integrates sophisticated features for both buck and boost operations within a single compact IC. This series is designed for applications requiring robust voltage regulation across varying input conditions, offering a reliable solution for complex power management needs.
