LTC3256HMSE#TRPBF

Overview

The LTC3256HMSE#TRPBF is a dual-channel switched capacitor step-down converter manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 38V and provides two independent regulated outputs. The device integrates a power-on reset sequencer for controlled startup timing. It utilizes an MSOP-16-EP package designed for surface-mount installation. The component supports operation across an extended temperature range from -40°C to +150°C, ensuring reliability in demanding industrial environments.

Feature Summary

• Dual-channel switched capacitor topology for independent output regulation
• Integrated power-on reset sequencer manages startup timing
• Extended thermal performance rated up to 150°C

Applications

• Industrial control systems requiring multiple isolated rails
• Automotive electronics with high thermal constraints
• Communication infrastructure power distribution

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when placing orders. Confirm the MSOP-16-EP footprint compatibility with your PCB layout. Ensure the supplier provides valid traceability documentation for Analog Devices components. Check current availability status as supply may be restricted. Validate that the operating voltage requirements align with the 5.5V to 38V input specification.

Selection Notes

Select this component when dual low-noise step-down voltages are required from a single wide-input source. The integrated sequencer simplifies design complexity compared to discrete solutions. Consider the thermal dissipation capabilities of the exposed pad package for high-current applications. Verify that the switched capacitor architecture meets the efficiency requirements for the target load conditions.
