LT8711IFE#TRPBF

Overview

The LT8711IFE#TRPBF is a multi-topology current mode PWM controller from Analog Devices Inc., housed in a 20-TSSOP package with an exposed pad. It supports synchronous buck, boost, SEPIC, ZETA, and asynchronous buck-boost configurations. The device operates within an input voltage range of 4.5 V to 42 V and features a switching frequency adjustable between 100 kHz and 750 kHz. It delivers a typical output current of 10 A and maintains a maximum duty cycle of 100%. The component functions as a non-isolated switching controller with an operating supply current of 2 mA.

Feature Summary

Supports multiple converter topologies including synchronous buck, boost, SEPIC, ZETA, and asynchronous buck-boost
Dual gate drive voltage inputs optimize gate driver efficiency
Current mode PWM control architecture for precise regulation

Applications

Automotive power systems
Industrial installations
High efficiency synchronous SEPIC converters

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the 20-TSSOP exposed pad package matches your PCB footprint requirements. Ensure the 42V maximum input rating aligns with your system's voltage headroom. Check that the -40°C to 125°C junction temperature range suits your thermal design constraints before finalizing procurement.

Selection Notes

Select this controller when flexible topology configuration is required without changing components. The dual gate drive input offers efficiency benefits over single-drive designs. Consider the 10A output capability and wide input voltage range for robust industrial or automotive applications. Verify compatibility with external MOSFETs for the desired current levels and switching frequencies up to 750kHz.

Part Context

This part belongs to the LT8711 family of multi-topology controllers. It shares core functionality with variants like LT8711EFE#PBF but differs in packaging and reel format. The device integrates advanced control features suitable for complex power conversion needs across various industries.
