Overview
The LT3724EFE#TRPBF is a high-voltage, current-mode switching regulator controller designed for medium-power DC/DC applications. It supports an input voltage range of 4V to 60V and delivers up to 75W output power at 24V. The device operates at a fixed switching frequency of 200kHz and features an internal high-voltage bias regulator. It achieves efficiencies up to 93% and functions within an operating temperature range of -40°C to +125°C.
Feature Summary
- Integrates an internal high-voltage bias regulator that allows simple startup and can be back-driven by the output to improve efficiency.
- Utilizes a fixed-frequency current-mode architecture for stable control in boost, buck, and SEPIC topologies.
- Supports wide input voltage ranges from 4V to 60V with low quiescent supply current.
Applications
- Industrial power supplies requiring high efficiency and low part count
- Automotive electronics systems operating within wide voltage ranges
- Telecommunications infrastructure power conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when reviewing distributor listings. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the component status is listed as Active. Cross-reference the full part number against official Analog Devices documentation to avoid confusion with similar variants like the LT3724EFE#PBF.
Selection Notes
Select this controller for designs requiring a single IC solution for boost, buck, or SEPIC converters without needing external bias generation. It is suitable for applications where input voltages vary significantly between 4V and 60V. Consider the 200kHz fixed frequency for EMI management and the internal bias regulator for simplified schematic design compared to discrete solutions.
Part Context
This component belongs to the LT3724 series of high-voltage controllers. It is distinct from lower-voltage regulators and non-controllers. The device is specifically engineered for isolated and non-isolated topologies in the medium-power segment, differentiating it from general-purpose LDOs or low-voltage synchronous controllers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Users should consult Analog Devices official documentation for direct replacements or pin-compatible alternatives.
