LTC3863EMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3863EMSE#TRPBF is a DC/DC switching controller manufactured by Analog Devices Inc., designed for buck and inverting topologies. It operates with an input voltage range of 3.5V to 60V and supports a switching frequency between 50kHz and 850kHz. The device provides one output channel with positive or negative output configuration capabilities. It features current limit, enable, frequency control, and soft start functions. Packaged in a 12-MSOP-EP (12-TSSOP) surface-mount package with an exposed pad, it ensures reliable operation across a junction temperature range of -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Supports both buck and inverting DC/DC converter topologies with single-inductor configurations.
• Enables conversion from positive input voltages to negative output voltages using a single inductor.
• Integrates comprehensive control features including current limiting, enable logic, frequency synchronization, and soft-start functionality.

DC DC Switching Controllers Applications

• Automotive power systems requiring robust voltage regulation
