LTC3863EMSE#PBF

DC DC Switching Controllers Overview

The LTC3863EMSE#PBF is a DC/DC switching controller manufactured by Analog Devices Inc., designed for inverting topologies. It converts a positive input voltage to a negative output using a single inductor. The device operates with an input supply range of 3.5V to 60V and supports adjustable switching frequencies between 50kHz and 850kHz. It features current mode control, soft start, and enable functions. The component is housed in a 12-MSOP-EP package with an exposed pad and is rated for operation from -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Supports inverting topology to generate negative outputs from positive inputs
• Includes programmable frequency control and soft-start capabilities
• Features integrated current limit protection and shutdown functionality

DC DC Switching Controllers Applications

• Evaluation board testing for low quiescent current inverting converters
• Systems requiring negative bias voltages derived from positive rails
• Industrial control circuits utilizing single-inductor inversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the MSOP-12 package variant matches design requirements. Check manufacturer documentation for recent production changes such as bond wire or marking updates. Ensure compatibility with intended thermal management solutions given the exposed pad requirement.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high input voltage ranges up to 60V. Consider the 12-MSOP-EP package for space-constrained designs needing thermal dissipation through the exposed pad. Evaluate external component selection against the specified frequency range to optimize efficiency and filter size.

DC DC Switching Controllers Part Context

This component belongs to the LTC3863 family of power management ICs. It is distinct from buck-only variants like the LTC3864 due to its inverting capability. The EMSE designation specifies the MSOP-12 package type within the broader product line.

DC DC Switching Controllers Replacement Considerations

LTC3863HMSE#PBF shares identical electrical specifications but differs in temperature rating. Verify thermal requirements before substitution.
