LTC3256MPMSE#PBF

Overview

The LTC3256MPMSE#PBF is a dual-output power management integrated circuit manufactured by Analog Devices Inc. It combines a synchronous step-down DC/DC converter with a low-dropout linear regulator in a single package. The switching regulator provides a non-isolated output, while the LDO offers a separate regulated rail. This component is designed for applications requiring efficient power conversion and clean voltage regulation from a single input source.

Feature Summary

• Integrates a high-efficiency synchronous buck converter with a precision low-dropout regulator
• Provides two independent regulated outputs from a single input supply
• Features thermal overload protection to safeguard against overheating conditions

Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial control systems needing isolated power segments
• Automotive infotainment and sensor interfaces

Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance when sourcing. Confirm the MP grade matches environmental requirements for your application. Ensure the MSOP-EP package footprint aligns with your PCB design constraints before ordering.

Selection Notes

Select this part when space efficiency is critical due to its integrated dual-regulator design. Consider the input voltage range and required output currents for both the switching and linear sections. Evaluate thermal performance needs as the device dissipates heat from both regulators within a compact package.

Part Context

This component belongs to the LTC3256 family of mixed-signal power management ICs. It serves as a solution for systems requiring both high-efficiency switching and low-noise linear regulation. The MP variant typically denotes military or extended temperature specifications compared to standard commercial grades.

Replacement Considerations

Direct substitutes include the LTC3256EMSE#PBF and LTC3256HMSE#PBF. Verify that the electrical characteristics and package dimensions are compatible with your existing design before swapping.
