LT3479EDE

Overview

The LT3479EDE is a high-performance switching regulator manufactured by Analog Devices Inc., housed in a DFN-14 surface-mount package. It operates as a boost converter with a maximum output current of 3A and a maximum output voltage of 42V. The device supports an input voltage range from 2.5V to 24V, featuring a programmable switching frequency between 200kHz and 3.5MHz. It includes integrated soft-start and inrush current protection, with a static current of 5mA. The component functions within a temperature range of -40°C to +85°C.

Feature Summary

Integrates soft-start functionality to manage initial power-up conditions
Includes built-in inrush current protection circuitry
Supports capacitor-programmable timing for flexible configuration

Applications

General purpose positive DC/DC conversion
Negative voltage generation via inverting topology
LED lighting driver circuits

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact specifications and compliance status. Check official Analog Devices resources for current availability and lifecycle status, as distribution channels may indicate limited supply or discontinuation. Ensure the component matches the required DFN-14 package and electrical ratings for the target design.

Selection Notes

Select this component when a compact solution is required for boosting or inverting voltages up to 42V with significant current capacity. The wide input range and adjustable frequency allow adaptation to various power sources. Consider the thermal performance and package size constraints relative to the 3A output capability during system integration.

Part Context

This part belongs to the LT3479 family of general-purpose positive/negative converters. It is designed for applications requiring efficient power management in small form factors. The device complements other Analog Devices power solutions by offering robust protection features alongside high efficiency in a leadless package.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. No direct public substitute part numbers are confirmed in the provided data. Verify pin compatibility and electrical parameters before considering any cross-reference components.
