Overview
The LT3480EDD#TRPBF is a micropower synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6 V to 36 V and delivers up to 2 A of output current. The device features a fixed 2.4 MHz switching frequency, enabling the use of small external components. It supports adjustable output voltages from 790 mV to 20 V. Key electrical specifications include a quiescent current of 70 uA and a shutdown supply current of 30 uA. It is housed in a 10-lead DFN package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Synchronous buck topology for high efficiency
- Fixed 2.4 MHz switching frequency
- Micropower operation with low quiescent current
- Integrated soft-start functionality
Applications
- Battery-powered portable equipment
- Industrial control systems
- Automotive electronics
- Point-of-load regulation modules
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches Analog Devices Inc. documentation exactly. Check RoHS compliance status via official datasheets. Ensure the DFN-10 package type aligns with PCB footprint requirements. Validate operating temperature ranges against application environmental conditions.
Selection Notes
Select this component for applications requiring wide input voltage ranges and high efficiency at moderate currents. The fixed 2.4 MHz frequency reduces passive component size compared to lower-frequency alternatives. Consider thermal performance due to the compact DFN package. Verify that the required output voltage falls within the 790 mV to 20 V adjustable range. Evaluate system standby power needs against the 70 uA quiescent current specification.
Part Context
This part belongs to the LT3480 series of micropower synchronous step-down regulators. It shares core architecture with variants like LT3480IMSE#PBF but differs in packaging and reel configuration. The series is designed for space-constrained designs requiring efficient power conversion from higher voltage rails to lower logic or sensor voltages.
Replacement Considerations
LT3480IMSE#PBF offers identical electrical performance in a 10-MSOP package. Verify pinout compatibility and thermal pad connectivity between DFN and MSOP packages before substitution. No other direct substitutes are confirmed in public documentation.
