LT3467AIDDB

Overview

The LT3467AIDDB is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It integrates a 1.1A switch and operates at a fixed switching frequency of 2.1MHz. The device supports an input voltage range from 2.2V to 16V and provides an adjustable output voltage between 1.255V and 40V. It features integrated soft-start functionality and is housed in an 8-lead DFN package.

Feature Summary

• Integrates a high-voltage 1.1A power switch with internal soft-start control
• Operates at a fixed 2.1MHz switching frequency for compact passive design
• Supports wide input voltage ranges suitable for single-cell lithium-ion applications

Applications

• Single Li-Ion cell to 5V boost converters
• 4-cell battery to 5V SEPIC converters
• 5V to 12V or 40V step-up converters

Procurement Notes

Verify the specific suffix (e.g., TRPBF, TRMPBF) against the required packaging format such as tape and reel or cut tape. Confirm RoHS compliance status and lead-free availability directly with the manufacturer or authorized distributors before finalizing procurement orders.

Selection Notes

Select this component when a fixed high-frequency operation is preferred over the standard LT3467's 1.3MHz variant. Ensure the application requires an input voltage up to 16V and benefits from the smaller passive components enabled by the 2.1MHz switching speed.

Part Context

This part belongs to the LT3467 family of switching regulators. It shares core architecture with the LT3467 but differs primarily in its optimized switching frequency. The family targets portable electronics requiring efficient power conversion from low-voltage sources.

Replacement Considerations

LT3467IDDB is a functional alternative with a different switching frequency.
