LTC3864MPMSE#TRPBF

DC DC Switching Controllers Overview

The LTC3864MPMSE#TRPBF is a high-voltage synchronous step-down DC/DC controller manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5V to 60V and supports adjustable output voltages down to 0.97V. The device features a fixed switching frequency of 200kHz, selectable via an external resistor, and includes programmable current limit and soft-start capabilities. Packaged in a 12-lead MSOP with an exposed thermal pad for enhanced heat dissipation, it is designed for industrial applications requiring low quiescent current and robust performance across wide temperature ranges.

DC DC Switching Controllers Feature Summary

• Supports 100% duty cycle operation for minimal dropout voltage at low input-to-output differentials
• Integrates precision current limit circuitry with foldback protection to safeguard against short circuits
• Features low quiescent current consumption to maintain efficiency during light-load conditions
• Includes programmable soft-start to control inrush current and output voltage ramp-up

DC DC Switching Controllers Applications

• Industrial automation power supplies
• Telecommunications infrastructure equipment
• Point-of-load regulation for microprocessors and FPGAs
• Battery-powered instrumentation systems

DC DC Switching Controllers Procurement Notes

Verify the specific suffix MPMS indicates military-grade qualification if required for your application. Confirm the package type matches your PCB footprint requirements. Check for RoHS compliance status on the latest datasheet. Ensure the supplier provides traceability documentation for critical components. Validate that the operating temperature range meets your system specifications.

DC DC Switching Controllers Selection Notes

Select this controller when a wide input voltage range up to 60V is necessary. Choose this part for designs requiring precise current limiting without external sensing resistors. Consider this component for space-constrained applications needing a compact MSOP package. Evaluate this option when low standby power consumption is a primary design constraint.

DC DC Switching Controllers Part Context

This component belongs to the LTC3864 family of high-voltage synchronous buck controllers. It shares functional similarities with other Linear Technology regulators but offers specific military-grade variants. The series is known for integrating gate drivers and control logic into a single compact package. It complements Analog Devices' portfolio of power management solutions for demanding environments.

DC DC Switching Controllers Replacement Considerations

Direct replacements include the standard commercial grade LTC3864HMSE#TRPBF or LTC3864IMSE#TRPBF. Verify pin compatibility and electrical specifications before substitution. Military versions may have stricter screening requirements than commercial equivalents.
