LT3579IFE-1#TRPBF

Overview

The LT3579IFE-1#TRPBF is a high-performance switching regulator IC manufactured by Analog Devices Inc. It integrates a 6A switch capable of operating in boost, inverting, Cuk, SEPIC, and flyback topologies. The device supports an input voltage range from 2.5V to 16V and provides an adjustable output voltage up to 42V. It features a programmable switching frequency between 200kHz and 2.5MHz. The component is housed in a 20-pin WQFN package with an exposed pad for thermal management.

Feature Summary

Integrates a high-current 6A power switch for efficient energy conversion across multiple DC/DC topologies.
Supports flexible circuit configurations including boost, inverting, Cuk, SEPIC, and flyback operations.
Includes comprehensive fault protection mechanisms to ensure system reliability under abnormal conditions.

Applications

Industrial control systems requiring isolated or inverted power rails
Automotive electronics utilizing wide input voltage ranges
Battery-powered equipment needing step-up or negative voltage generation

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component when designing circuits that require high current capability in non-standard topologies like Cuk or SEPIC. Evaluate thermal performance requirements due to the integrated 6A switch operation. Consider the adjustable frequency range to optimize external component sizes and electromagnetic interference characteristics.
