LT3579EFE#PBF

Overview

The LT3579EFE#PBF is a high-performance switching regulator IC manufactured by Analog Devices Inc., housed in a 20-lead TSSOP package. It integrates a 6A switch to support boost, SEPIC, and inverting DC/DC converter topologies. The device operates with an input voltage range of 2.5V to 16V and provides an adjustable output voltage up to 42V. Key electrical parameters include a switching frequency range of 200kHz to 2.5MHz, a quiescent current of 5mA, and operation across a temperature range of -40°C to +125°C.

Feature Summary

Integrates a 6A power switch for high-current capability
Supports multiple topologies including boost, SEPIC, and inverting configurations
Features programmable switching frequency from 200kHz to 2.5MHz
Includes internal soft-start and cycle-by-cycle current limiting

Applications

Automotive electronics requiring isolated or inverted supplies
Industrial systems needing flexible DC/DC conversion
Battery-powered devices utilizing boost or SEPIC architectures

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for this Analog Devices component to guarantee authenticity and quality standards.

Selection Notes

Select this component when designing circuits requiring a single-inductor solution for boost, SEPIC, or inverting applications. The integrated 6A switch allows for compact designs without external pass transistors. Consider the 200kHz to 2.5MHz frequency range for optimizing inductor size versus efficiency trade-offs in space-constrained environments.

Part Context

This part belongs to the LT3579 family of monolithic switching regulators designed for versatile power conversion needs. It serves as a robust alternative to discrete solutions, offering simplified design implementation. The device is categorized under PMIC DC-DC Switching Regulators within the Analog Devices portfolio.
