LT3574EMS#PBF

Overview

The LT3574EMS#PBF is a monolithic switching regulator designed for isolated flyback topologies, eliminating the need for opto-isolators or third windings. It features an integrated 60V/0.65A switch and operates with a switching frequency range of 40kHz to 1MHz. The device supports input voltages from 3V to 40V and delivers adjustable output regulation. It functions within an operating temperature range of -40°C to 125°C (TA) and utilizes a 16-lead MSOP package with exposed pad for surface mount mounting.

Feature Summary

Eliminates requirement for opto-isolators and auxiliary transformer windings in isolated designs
Integrates high-voltage power switch for compact board space utilization
Supports wide input voltage range suitable for diverse power sources
Enables precise output voltage adjustment through external resistor network

Applications

Isolated DC-DC converter designs requiring galvanic isolation
Industrial control systems with multiple isolated supply rails
Medical equipment power supplies adhering to safety standards
Telecommunications infrastructure requiring reliable isolated conversion

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the 16-lead MSOP EP configuration. Ensure RoHS compliance status aligns with project requirements. Validate lot codes and traceability documentation provided by authorized distributors. Cross-reference ordering part numbers to ensure exact functional equivalence.

Selection Notes

Evaluate thermal performance requirements given the integrated switch capabilities and operating temperature limits. Consider PCB layout constraints associated with the MSOP package footprint. Assess input voltage stability within the specified 3V to 40V range for target applications. Verify that required isolation voltage levels meet system safety standards without additional components.

Part Context

This component belongs to Analog Devices' family of isolated flyback controllers designed to simplify power supply design. It replaces traditional solutions requiring separate optocouplers and feedback loops. The series focuses on reducing component count and improving reliability in isolated power conversion applications across industrial and commercial sectors.
