Overview
The LT3800IFE#TRPBF is a high-voltage synchronous current mode step-down switching regulator controller manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 200 kHz and supports an input voltage range from 4 V to 60 V. The device provides one output channel capable of driving up to 15 A. It features a quiescent current of 100 uA and functions within a temperature range of -40°C to +125°C. Packaged in a 16-lead TSSOP with an exposed pad, it is designed for efficient DC/DC conversion applications requiring high voltage tolerance.
Feature Summary
- High-voltage synchronous buck controller architecture
- Fixed 200 kHz switching frequency operation
- Supports negative or positive output configurations
- Integrated internal VCC regulator for startup
Applications
- Industrial power supply systems
- Point-of-load regulation modules
- Telecommunications equipment power distribution
- Automotive electronics power management
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the 16-TSSOP-EP package matches the target PCB footprint requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check RoHS compliance documentation if required for specific regulatory standards.
Selection Notes
Select this controller for designs requiring wide input voltage ranges up to 60 V. Consider the 200 kHz frequency for balancing component size and efficiency. Evaluate thermal performance due to the exposed pad package design. Ensure external N-channel MOSFETs are compatible with the gate drive capabilities provided by the IC.
Part Context
This component belongs to the LT3800 series of high-voltage synchronous step-down controllers. It shares functional similarities with variants like the LT3800EFE but differs in packaging and shipping format. The series is characterized by its ability to handle high input voltages while maintaining precise current mode control for stable output regulation.
Replacement Considerations
Direct substitutes include other Analog Devices high-voltage buck controllers such as the LT3800IFE#PBF for tube packaging. Cross-reference pinouts and electrical specifications carefully before replacing with components from different manufacturers.
