Overview
The LT3663EMS8E-5#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 7V to 36V and provides a fixed output voltage of 5V. The device delivers a maximum output current of 1.2A with a typical switch current rating of 2A. It functions at a switching frequency of 1100kHz. The component supports an operating temperature range from -40°C to +125°C and is housed in an 8-pin MSOP EP package.
Feature Summary
- Integrates internal high-side and synchronous low-side power switches for high efficiency.
- Features programmable output current limit to control system power dissipation.
- Utilizes current mode architecture for precise regulation.
- Includes shutdown capability for power management.
Applications
- Automotive electronics power distribution
- Industrial control systems
- Embedded computing power supplies
Procurement Notes
Verify the specific suffix #TRPBF confirms tape and reel packaging rather than tube. Confirm the manufacturer part number matches Analog Devices official documentation. Ensure the order includes the correct automotive grade designation if required by the application environment. Cross-reference the datasheet revision date against the supplier's certificate of compliance.
Selection Notes
Select this component when a fixed 5V output is required from a 7V to 36V input source. Choose this model over adjustable variants if a stable 5V rail is necessary without external feedback resistors. Consider the 1.2A continuous current capability and 2A peak switch rating for load requirements. Evaluate the 1100kHz switching frequency for inductor size constraints compared to lower frequency alternatives.
Part Context
This part belongs to the LT3663 family of high voltage synchronous buck converters. It shares architectural similarities with the LTC3631 but offers higher current capacity. The EMS8E package denotes an exposed pad MSOP form factor suitable for surface mount assembly. The TRPBF suffix indicates reel-based delivery for automated placement.
Replacement Considerations
LT3663EMS8E-5#PBF serves as the tube-packaged equivalent of this reel-delivered component. Both parts share identical electrical specifications, pinout, and thermal characteristics. Verify that the manufacturing lot and packaging format align with production line requirements before substitution.
