Operating temperatures range from -55°C to +150°C TJ.
Feature Summary
- Supports isolated flyback topology without requiring opto-isolators
- Provides high average gate drive current for efficient switching
- Operates in boundary mode for optimized performance
Applications
- Industrial power supplies
- Distributed power systems
- Battery chargers
Procurement Notes
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the MPMS variant meets military temperature specifications if required for harsh environments. Ensure the 16-TFSOP package dimensions align with PCB layout constraints. Cross-reference the datasheet revision D for accurate electrical characteristics before finalizing design.
Selection Notes
Select this component for applications requiring high input voltages up to 100V. The absence of opto-isolator requirements simplifies transformer design and improves reliability. Consider the 1.9A gate drive capability for driving external MOSFETs efficiently. Verify thermal management strategies for the specified operating temperature range.
Part Context
This part belongs to the LT3748 series of switching regulators. It is specifically engineered for high-power isolated flyback converters. The MPMS designation indicates a military-grade temperature range extension compared to standard commercial variants.
Replacement Considerations
LT3748HMS#PBF serves as a verified substitute within the same family. Both parts share identical functional specifications and pinouts. Ensure the replacement matches the required packaging format and temperature grade.
