LTC3256IMSE#TRPBF

Overview

The LTC3256IMSE#TRPBF is a dual-output power management IC from Analog Devices, integrating one synchronous step-down (buck) converter and one low-dropout (LDO) regulator. It operates with an input voltage range of 5.5V to 38V and delivers up to 350mA of output current. The device is housed in a compact 16-lead MSOP package and supports surface-mount installation. It functions within an extended temperature range of -40°C to 150°C, providing efficient DC/DC conversion alongside regulated linear output for mixed-signal applications.

Feature Summary

• Integrates a synchronous buck converter and an LDO regulator in a single package
• Supports wide input voltage ranges for flexible power supply designs
• Provides high thermal performance suitable for demanding operating environments

Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial control systems with mixed analog and digital loads
• Communication equipment needing isolated or separate regulation stages

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure compatibility with design specifications. Check current availability status as supply may be limited. Ensure the receiving facility handles ESD-sensitive components appropriately during receipt and storage.

Selection Notes

Choose this component when space constraints require combining switching and linear regulation. It is suitable for designs needing both high efficiency from the buck stage and low noise from the LDO. Consider the 350mA current limit and input voltage range against system requirements. Evaluate thermal dissipation needs given the MSOP package size and operating temperature limits.

Part Context

This part belongs to the LTC3256 series of integrated power management solutions. It represents Analog Devices' approach to consolidating power functions into small footprints. The IMSE designation specifies the industrial temperature grade and MSOP package type. This series targets applications where board real estate is limited but multiple regulated outputs are necessary.
