Overview
The LT8711EFE#PBF is a micropower synchronous multi-topology DC-DC controller IC manufactured by Analog Devices Inc. It supports buck, boost, buck-boost, SEPIC, and ZETA configurations. The device features a 42V input capability and utilizes current mode PWM control. 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 buck-boost
- Features dual gate drive voltage inputs to optimize gate drive performance
- Designed as a micropower solution for energy-efficient applications
Applications
- Portable battery-powered equipment requiring flexible topology options
- Industrial systems needing isolated or non-isolated power conversion
- Automotive electronics operating within specified input voltage ranges
Procurement Notes
Verify the exact part number LT8711EFE#PBF against official Analog Devices documentation to ensure compatibility. Confirm package type is 20-TSSOP-EP. Check for RoHS compliance status indicated by the #PBF suffix. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the component.
Selection Notes
Select this controller when application requires flexibility between buck, boost, and SEPIC modes without changing components. Consider the 42V maximum input rating for system design margins. Evaluate thermal requirements due to the TSSOP-EP package. Compare power consumption needs against other Analog Devices controllers if ultra-low quiescent current is critical.
Part Context
The LT8711 belongs to Analog Devices' family of multi-topology switching controllers. It shares functional similarities with other Linear Technology derived parts but offers specific integration for micropower applications. The EFE suffix denotes the specific package and temperature range variant within the broader LT8711 product line.
Replacement Considerations
LT8711EFE#TRPBF is a tape-and-reel version of the same electrical specification. Verify pinout and thermal characteristics remain identical before substitution. No direct cross-brand replacements are confirmed in public documentation.
