LT8711IFE#PBF

Overview

The LT8711IFE#PBF is a micropower synchronous multitopology PWM controller from Analog Devices Inc. It supports input voltages from 4.5V to 42V and operates at switching frequencies between 100kHz and 750kHz. The device features a maximum duty cycle of 100% and provides one output. It is housed in a 20-TSSOP-EP package with an exposed pad for thermal management.

Feature Summary

• Supports multiple converter topologies including synchronous buck, boost, SEPIC, ZETA, and non-synchronous configurations
• Integrated synchronous rectification control for improved efficiency
• Wide input voltage range capability up to 42V

Applications

• Industrial power supplies
• Distributed power systems
• Battery-powered equipment requiring flexible topology conversion

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS status. Confirm the 20-TSSOP-EP package type matches your PCB footprint requirements. Ensure the operating temperature range of -40°C to +125°C meets your environmental specifications before finalizing procurement.

Selection Notes

Select this component when a single controller must support various DC-DC conversion topologies without changing hardware architecture. It is suitable for designs requiring wide input voltage ranges and high efficiency through synchronous rectification. Consider the 100kHz to 750kHz frequency range for balancing size and efficiency.

Part Context

This part belongs to the LT8711 family of micropower synchronous multitopology controllers. It is designed to replace discrete solutions or fixed-topology controllers by offering configurable operation modes. The device integrates essential control loops for stable regulation across different circuit configurations.
