Overview
The LT3480IMSE#TRPBF is a micropower switching regulator from Analog Devices, operating as a synchronous buck converter. It accepts 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 provides an adjustable output voltage between 790 mV and 20 V with a single output configuration. Quiescent current is specified at 70 µA during operation and drops to 30 µA in shutdown mode. The component is housed in a 10-lead MSOP package with an exposed pad for thermal management.
Feature Summary
- Integrated synchronous rectification eliminates the need for external Schottky diodes, improving efficiency and reducing component count.
- Fixed high-frequency switching allows for the use of compact inductors and capacitors, minimizing overall solution size.
- Micropower architecture ensures low standby consumption, making it suitable for battery-powered applications requiring extended runtime.
Applications
- Portable instrumentation systems
- Industrial control modules
- Battery-operated equipment
Procurement Notes
Verify the suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the IMSE variant meets industrial temperature requirements. Ensure compatibility with the 10-MSOP footprint during PCB layout. Cross-reference datasheet revisions for any pinout or electrical specification updates before finalizing procurement.
Selection Notes
Select this part for designs requiring a wide input voltage range and high efficiency in a small form factor. The fixed 2.4 MHz frequency simplifies EMI filtering compared to lower-frequency alternatives. Consider thermal performance due to the exposed pad requirement. Verify that the required output voltage falls within the adjustable range supported by the internal feedback network.
Part Context
This component belongs to the LT3480 series of micropower synchronous buck regulators. It shares architectural similarities with other members of the family but is distinguished by its specific package type and switching frequency. The series is designed for applications demanding high efficiency and minimal quiescent current across varying load conditions.
Replacement Considerations
LT3480IMSE#PBF is a tube-packaged version of the same functional device. LT3480HMSE#TRPBF offers an extended maximum junction temperature rating. Verify package dimensions and thermal characteristics when substituting between these variants.
