LT3467AIS6#TRPBF

Overview

The LT3467AIS6#TRPBF is a high-efficiency boost DC/DC converter manufactured by Analog Devices Inc. It integrates a 1.1A power switch and operates with an input voltage range of 2.2V to 16V, delivering a maximum output voltage of 40V. The device features a fixed switching frequency of 2.1MHz, which enables the use of compact external components. It includes an internal soft-start function to limit inrush current during startup. The component is housed in a TSOT-23-6 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates a robust 1.1A power switch capable of handling high peak currents for efficient power conversion.
• Features a high 2.1MHz switching frequency that facilitates the use of miniature inductors and capacitors.
• Includes an internal soft-start mechanism to control ramp-up time and minimize start-up stress on the circuit.

Applications

• Battery-powered portable devices requiring step-up voltage regulation
• Industrial sensor interfaces needing stable supply rails
• Communication modules utilizing single-cell or multi-cell battery inputs

Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free compliance. Confirm availability status as distribution channels may indicate limited stock or discontinuation risks. Ensure the operating environment matches the specified industrial temperature grade before finalizing procurement orders.

Selection Notes

Select this component when a compact boost solution is required with a 1.1A current capability. The 2.1MHz frequency is optimal for minimizing passive component size compared to lower-frequency alternatives. Ensure the input source can sustain the required current without dropping below the 2.2V minimum threshold during peak load conditions.

Part Context

This part belongs to the LT3467A family of switching regulators designed for space-constrained applications. It shares architectural similarities with other members of the series but is distinguished by its specific A-grade temperature rating and fixed 2.1MHz frequency configuration within the TSOT-23-6 footprint.

Replacement Considerations

Direct pin-compatible substitutes within the same package include other variants of the LT3467 family, such as the LT3467IS6, though switching frequencies may differ. Verify electrical parameters carefully when cross-referencing with older LT3467 models to ensure compatibility with existing design constraints.
