Overview
The LT3430IFE#TRPBF is a high-voltage switching regulator manufactured by Analog Devices Inc., designed for buck and inverting topologies. It operates with an input voltage range from 5.5 V to 60 V and delivers an output current of 2.75 A. The device features a fixed switching frequency of 200 kHz and supports adjustable output voltages. It is housed in a 16-lead TSSOP package with an exposed pad (TSSOP-EP-16) for surface mount installation. The component functions within a temperature range of -40°C to +125°C and includes shutdown capabilities.
Feature Summary
- Supports both buck and inverting converter topologies for versatile power conversion needs.
- Handles high input voltages up to 60 V, suitable for industrial and automotive applications.
- Integrated 2.75 A switch capability reduces external component count and board space.
- Fixed 200 kHz switching frequency allows for the use of small passive components.
Applications
- Industrial control systems requiring isolated or non-isolated high-voltage regulation
- Automotive electronics operating on 12V or 24V nominal bus systems
- Point-of-load regulation in telecommunications infrastructure
- Battery-powered equipment needing efficient step-down conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the TSSOP-EP-16 footprint matches your PCB layout requirements. Check for any recent product change notices regarding epoxy or material updates that may affect long-term reliability or assembly processes.
Selection Notes
Select this component when a single-chip solution is needed for high-input voltage buck or inverting applications. It is appropriate for designs requiring moderate output current without external pass transistors. Consider the 200 kHz frequency as a balance between efficiency and passive size. Evaluate thermal performance based on the exposed pad design for adequate heat dissipation in enclosed environments.
Part Context
This part belongs to the LT3430 series of high-voltage DC/DC converters from Analog Devices. The series is characterized by its ability to operate directly from high-voltage sources common in industrial and automotive sectors. The IFE variant specifically denotes the TSSOP-EP-16 package option, which provides improved thermal performance compared to standard packages. It serves as a compact alternative to discrete solutions for high-voltage regulation tasks.
Replacement Considerations
LT3430EFE#TRPBF offers identical electrical specifications but utilizes a standard TSSOP-16 package without the exposed pad, requiring different thermal management strategies.
