LTC3872HTS8-1#TRMPBF

DC DC Switching Controllers Overview

The LTC3872HTS8-1#TRMPBF is a synchronous boost DC/DC controller from Analog Devices, housed in an 8-lead TSOT-23 package. It operates with an input voltage range of 2.75 V to 9.8 V and supports switching frequencies up to 550 kHz. The device features current mode control without requiring a sense resistor, offering a quiescent current of 250 µA. It provides shutdown functionality and is rated for operation between -40°C and +125°C.

DC DC Switching Controllers Feature Summary

• Current mode control architecture eliminates the need for external current sense resistors
• Integrated synchronous rectification for improved efficiency in compact designs
• Shutdown pin enables low power consumption during inactive periods

DC DC Switching Controllers Applications

• Battery-powered portable electronics
• Industrial sensor nodes
• Communication equipment power stages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix HTS8-1 against your schematic requirements to ensure correct package and temperature grade compatibility. Confirm that the 550 kHz switching frequency aligns with your passive component selection. Ensure the input voltage range covers your minimum battery discharge curve. Check for RoHS compliance documentation if required by your manufacturing standards.

DC DC Switching Controllers Selection Notes

Select this component when space constraints necessitate a small TSOT-23 footprint for boost applications. It is suitable for designs requiring high efficiency without the cost and board area of sense resistors. Consider the 250 µA quiescent current for battery life calculations. Ensure the output voltage capability meets the load requirements within the specified input range.

DC DC Switching Controllers Part Context

This part belongs to the LTC3872 family of no-RSENSE synchronous boost controllers. It shares functional similarities with other members like the LTC3872ITS8-1 but differs in thermal performance and package variant. The HTS8-1 designation indicates the specific TSOT-23 package optimized for higher thermal dissipation compared to standard variants.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LTC3872ITS8-1#TRMPBF for identical electrical performance in a standard TSOT-23 package. For larger packages, the LTC3872HFD-1#PBF offers similar functionality in an 8-lead DFN. Verify pinout compatibility before substitution.
