Overview
The LT3844IFE#PBF is a high-voltage, current mode switching regulator controller designed for medium power applications. It supports Buck, Boost, Inverting, and SEPIC topologies with a single output. The device operates within an input voltage range of 4V to 60V and delivers up to 5A output current. It features a programmable switching frequency between 100 kHz and 500 kHz. The component functions in temperatures from -40°C to +125°C, housed in a TSSOP-16 package.
Feature Summary
- Supports multiple converter topologies including Buck, Boost, Inverting, and SEPIC configurations
- Utilizes current mode control architecture for stable regulation
- Features programmable operating frequency for flexible design optimization
Applications
- Industrial power supplies requiring wide input ranges
- Automotive electronics systems
- Telecommunications infrastructure equipment
- Battery-powered devices needing step-up or step-down conversion
Procurement Notes
Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the TSSOP-16 package type matches your PCB footprint requirements. Ensure the manufacturer is Analog Devices Inc. Check for obsolescence status as availability may be limited compared to newer generations.
Selection Notes
Select this controller when a wide 4V to 60V input range is required for non-isolated DC/DC conversion. Choose the LT3844IFE#PBF for designs needing current mode control to handle transient loads effectively. Consider the 5A output capability and programmable frequency range for efficiency optimization in medium-power applications.
Part Context
This component belongs to the LT3844 series of high-voltage switching regulators. It is part of Analog Devices' portfolio of power management ICs focused on efficient energy conversion. The device serves as a core controller for external MOSFETs in various power supply architectures.
Replacement Considerations
LT3844IFE#TRPBF offers identical electrical specifications but utilizes tape-and-reel packaging instead of tube packaging. Verify that the functional performance remains unchanged between these packaging variants.
