LT3467IDDB#TRPBF

Overview

The LT3467IDDB#TRPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.2 V to 16 V and delivers up to 1.1 A output current. The device features a fixed switching frequency of 1.3 MHz and supports output voltages up to 40 V. It includes integrated soft-start functionality and a shutdown pin for power management. The component functions within a temperature range of -40°C to +125°C and is housed in an 8-lead DFN package.

Feature Summary

• Integrated synchronous rectification for high efficiency
• Built-in soft-start limits inrush current during startup
• Shutdown control minimizes quiescent current consumption

Applications

• Single-cell lithium-ion battery powered systems
• Portable instrumentation requiring step-up conversion
• Industrial control modules operating from low voltage sources

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation as distributor listings may vary. Ensure the DFN-8 package footprint matches the design layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 1.3 MHz switching frequency is required to minimize external passive size. The 1.1 A current limit suits applications needing moderate boost capability without excessive heat dissipation. Verify that the 16 V maximum input voltage aligns with the source supply characteristics.

Part Context

This part belongs to the LT3467 series of synchronous boost converters. It shares architectural similarities with the LT3467A, which utilizes a higher 2.1 MHz frequency. The IDDB designation specifies the industrial temperature grade and the specific DFN-8 package variant offered by Analog Devices.

Replacement Considerations

LT3467AIDDB#TRPBF offers identical functionality but operates at a 2.1 MHz switching frequency instead of 1.3 MHz.
