LT3575EFE#TRPBF

Overview

The LT3575EFE#TRPBF is a monolithic switching regulator designed for isolated flyback converter applications. It integrates a high-voltage NPN transistor and control circuitry into a single package. The device supports an input voltage range of 10V to 28V and provides a regulated output, such as 5V at up to 2A. It features a fixed internal switching frequency of 1MHz, eliminating the need for external timing components. The component operates within a temperature range of -40°C to 125°C and utilizes a 16-lead SSOP package with exposed pad for thermal management.

Feature Summary

Integrates a 60V, 2.5A NPN power transistor with dedicated flyback controller logic
Fixed 1MHz switching frequency operation removes requirement for external oscillator or transformer turns ratio selection
Includes cycle-by-cycle current limiting and thermal shutdown protection mechanisms

Applications

Isolated DC-DC power supplies for industrial equipment
Battery-powered systems requiring galvanic isolation
General-purpose isolated power conversion modules

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability records. Cross-reference the exact part number against the latest Analog Devices datasheet to confirm pinout and electrical specifications match design requirements.

Selection Notes

Select this component for designs requiring a compact, integrated solution for low-to-medium power isolated conversions. The fixed frequency simplifies transformer design compared to variable frequency controllers. Evaluate thermal performance carefully due to the integrated power transistor. Consider the 1MHz frequency for trade-offs between component size and electromagnetic interference. Verify input voltage ranges align with system supply characteristics.

Part Context

This part belongs to the LT3575 family of monolithic switching regulators. These devices are engineered specifically for isolated flyback topologies. The family offers integrated power switches to reduce board space and component count. They are commonly used in applications where cost and size efficiency are critical for isolated power stages.
