Overview
The LT3467IS6#TRMPBF is a switching regulator from Analog Devices Inc. housed in a TSOT-23-6 package. It integrates a 42V, 1.1A switch with soft-start functionality and operates at a 1.3MHz frequency. The device supports Boost, Flyback, and SEPIC topologies with an adjustable output voltage range of 1.255V to 40V. Input voltage ranges from 2.2V to 16V, supporting single-cell Li-ion or multi-cell battery applications.
Feature Summary
- Integrates a high-voltage 42V switch capable of delivering 1.1A current
- Supports multiple converter topologies including Boost, Flyback, and SEPIC
- Features integrated soft-start to limit inrush current during startup
Applications
- Single lithium-ion cell to 5V step-up conversion
- Multi-cell battery to 5V SEPIC conversion
- Low voltage input to higher voltage boost regulation
Procurement Notes
Verify the specific suffix #TRMPBF indicates cut tape packaging when ordering. Confirm the operating temperature range meets system requirements as the device supports -40°C to +125°C junction temperature. Ensure compatibility with the required output voltage adjustment range and input supply constraints before finalizing procurement.
Selection Notes
Select this component for designs requiring a compact solution with integrated power switching. The 1.3MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the maximum switch voltage rating and current limits when designing for heavy loads or transient conditions.
Part Context
This part belongs to the LT3467 series of DC/DC converters. It is designed for space-constrained portable applications where efficiency and small footprint are critical. The series offers flexibility through configurable topologies, making it suitable for various battery-powered systems.
Replacement Considerations
Check for direct pin-compatible replacements within the LT3467 family if different packaging or temperature grades are needed. Verify that alternative parts maintain the same 42V switch rating and 1.3MHz switching frequency to ensure circuit stability.
