Overview
The LT3430EFE#PBF is a monolithic step-down DC/DC switching converter manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 60V and provides an adjustable output voltage starting from 1.219V up to 57.6V. The device features a 3A internal power switch and supports a fixed switching frequency of 200kHz. It utilizes a 16-TSSOP package with an exposed pad for thermal management. The component is designed for applications requiring compact space and wide input voltage flexibility.
Feature Summary
- Integrates a high-voltage 3A power switch capable of handling inputs up to 60V
- Supports both Buck and SEPIC topologies for versatile conversion requirements
- Utilizes a thermally enhanced 16-TSSOP package for efficient heat dissipation
Applications
- Industrial control systems requiring isolated or non-isolated power stages
- Automotive electronics operating within wide voltage fluctuation ranges
- Distributed power architectures in telecommunications equipment
Procurement Notes
Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when ordering. Confirm that the EFE suffix corresponds to the extended temperature grade (-40°C to 125°C) rather than the industrial grade. Ensure compatibility with the 16-TSSOP-EP footprint during PCB layout. Cross-reference the latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement specifications.
Selection Notes
Select this component when a single IC solution is needed for high-input voltage buck conversion without external MOSFETs. The 200kHz frequency offers a balance between component size and efficiency. Consider the exposed pad requirement for thermal performance. Compare against the LT3430IFE variant if different temperature ratings are required. Ensure the load current does not exceed the 3A internal switch limit under all operating conditions.
Part Context
The LT3430EFE#PBF belongs to the LT3430 family of high-voltage switching regulators. This series is designed to replace discrete solutions in space-constrained designs. It integrates the controller, driver, and power switch into a single chip. The family includes variants like the LT3430IFE and LT3430EFE-1, differing primarily in temperature grades and specific electrical tolerances defined by Analog Devices.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pin-to-pin compatibility and electrical parameters with potential alternatives such as other high-voltage buck converters from Analog Devices or competitors before substitution.
