LT3467AEDDB#TRMPBF

Overview

The LT3467AEDDB#TRMPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.3V to 16V and delivers up to 225mA of output current. The device features a fixed switching frequency of 1.3MHz and supports adjustable output voltages from 2.3V to 40V. Packaged in an 8-lead DFN (3x2mm) surface-mount case, it functions within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates a synchronous power switch for high efficiency in compact designs
• Includes internal compensation to minimize external component count
• Features adjustable switching frequency for optimization of inductor size and efficiency

Applications

• Portable battery-powered equipment
• Single-cell lithium-ion battery systems
• Automotive electronics requiring wide input voltage ranges

Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging when ordering. Confirm the A-grade temperature rating aligns with system requirements. Ensure the 8-DFN footprint matches the PCB layout constraints. Cross-reference the datasheet revision date to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring a small solution size and high efficiency from single-cell sources. The integrated synchronous rectifier reduces external losses compared to non-synchronous alternatives. Consider the 1.3MHz frequency trade-off between inductor size and EMI performance relative to other family members.

Part Context

This part belongs to the LT3467 family of boost converters designed for space-constrained portable applications. It shares architectural similarities with the LT3467A but may differ in specific electrical characteristics or temperature grades. The DFN package facilitates thermal dissipation while maintaining a low profile suitable for modern consumer electronics.

Replacement Considerations

LT3467IDDB#TRMPBF is a documented substitute within the same series.
