LT3579IFE#TRPBF

Overview

The LT3579IFE#TRPBF is a synchronous boost, inverting, and SEPIC DC/DC converter controller manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 16V and supports output voltages up to 42V. The device integrates a 6A switch and offers adjustable switching frequencies from 200kHz to 2.5MHz. It features soft-start capability, cycle-by-cycle current limiting, and power good indication. Packaged in a 28-lead TSSOP with an exposed pad for thermal dissipation, it functions within a temperature range of -40°C to 125°C.

Feature Summary

Integrates a high-current 6A synchronous switch for efficient power conversion
Supports multiple topologies including boost, inverting, and SEPIC configurations
Includes built-in soft-start and comprehensive fault protection mechanisms

Applications

Industrial control systems requiring flexible voltage regulation
Battery-powered equipment needing extended runtime through efficient conversion
Automotive electronics operating under variable input conditions

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing components. Confirm that the part number matches the exact pinout and thermal requirements of your design. Ensure compatibility with the intended switching frequency settings. Check for RoHS compliance status if required by your manufacturing standards. Validate supplier authenticity to avoid counterfeit devices.

Selection Notes

Choose this component when designing circuits that require a single controller to handle boost, inverting, or SEPIC topologies. It is suitable for applications demanding high output currents up to 6A with adjustable frequency. Consider the thermal performance of the TSSOP package for heat dissipation needs. Evaluate the input voltage range against your power source specifications.

Part Context

This controller belongs to the LT3579 family of power management ICs designed for versatile DC/DC conversion. It complements other Analog Devices solutions by providing multi-topology flexibility in a compact form factor. The series targets applications where space constraints and efficiency are critical priorities.
