LT3579EFE-1#TRPBF

Overview

The LT3579EFE-1#TRPBF is a switching regulator IC manufactured by Analog Devices Inc. It functions as a boost or inverting DC/DC converter with an integrated fault protection mechanism. The device features a 6A switch current capability and operates within an input voltage range of 2.5V to 16V. It supports adjustable output voltages starting from 1.215V, with a maximum switch voltage rating of 42V. The unit utilizes a 20-TSSOP package with exposed pad for thermal management.

Feature Summary

Integrates a high-current 6A power switch for efficient energy conversion
Supports multiple topologies including boost and inverting configurations
Includes built-in fault protection circuitry for system reliability

Applications

Industrial power supply systems requiring isolated or inverted rails
Battery-powered equipment needing voltage step-up capabilities
General-purpose DC/DC conversion in compact electronic modules

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout and functional compatibility. Ensure that the requested component matches the exact electrical specifications required for the target application design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and sourcing channels before finalizing procurement orders.

Selection Notes

Select this component when a robust solution for boosting or inverting voltage is required with significant current handling capacity. Consider the thermal performance provided by the TSSOP package with exposed pad for heat dissipation. Evaluate the input voltage range against the source availability to ensure stable operation under varying load conditions without exceeding the 42V switch voltage limit.

Part Context

This part belongs to the LT3579 family of switching regulators designed for versatile power conversion tasks. It shares architectural similarities with other Analog Devices power management ICs but is distinct in its specific integration of a 6A switch and fault protection features. The product line targets applications demanding reliable DC/DC conversion in space-constrained environments.
