Overview
The LT3467EDDB#TRPBF is a synchronous boost DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.2V to 16V and delivers up to 1.1A output current. The device supports adjustable output voltages up to 40V and utilizes a fixed switching frequency of 2.1MHz. It features integrated soft-start functionality and operates within a temperature range of -40°C to +125°C. The component is housed in an 8-lead DFN package.
Feature Summary
- Synchronous rectification for high efficiency
- Integrated soft-start limits inrush current
- Fixed 2.1MHz switching frequency
Applications
- Portable battery-powered equipment
- Single-cell lithium-ion battery systems
- General-purpose step-up power supplies
Procurement Notes
Verify the specific suffix against official documentation, as variations may exist between TRPBF and TRMPBPF packaging or lead-free designations. Confirm availability status directly with authorized distributors, as supply levels fluctuate. Ensure the ordering part number matches the required package type and RoHS compliance specifications before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring a compact solution for stepping up single-cell lithium-ion battery voltages. The 2.1MHz frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Verify that the required output voltage does not exceed the 40V maximum limit and that the load current remains within the 1.1A continuous rating.
Part Context
This part belongs to the LT3467 family of synchronous boost converters designed for portable applications. It shares core topology with other members but differs in package configuration and thermal characteristics. The EDDB suffix indicates a specific 8-lead DFN footprint optimized for surface-mount assembly in space-constrained designs.
Replacement Considerations
LT3467AIDDB#TRPBF offers similar electrical performance with potential minor parameter variations. LT3467EDDB#TRMPBF provides identical functionality with different reel packaging options.
