LT3573IMSE#TRPBF

Overview

The LT3573IMSE#TRPBF is an isolated flyback converter controller manufactured by Analog Devices Inc., designed to operate without an opto-coupler. It accepts input voltages ranging from 3V to 40V and provides a single adjustable output of 1.23V with a maximum current capability of 1.85A. The device is housed in a 16-pin MSOP package with an exposed pad (EP) and is rated for automotive applications. It supports switching frequencies up to 1MHz and operates within a junction temperature range of -40°C to 125°C.

Feature Summary

Eliminates the need for an opto-coupler in isolated flyback topologies through integrated feedback mechanisms.
Supports wide input voltage ranges suitable for diverse power supply architectures.
Includes built-in protection features such as cycle-by-cycle current limiting and thermal shutdown.

Applications

Automotive electronics requiring isolated power conversion
Industrial control systems needing galvanic isolation
Telecommunications equipment utilizing flyback converters

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the IMSE variant meets the required industrial temperature specifications compared to other grade variants. Ensure compatibility with the intended PCB footprint for the 16-MSOP EP package. Cross-reference the datasheet for any recent production changes or pinout updates before finalizing procurement.

Selection Notes

Select this component when designing isolated flyback converters that require elimination of opto-couplers to improve reliability and reduce component count. It is suitable for applications demanding high efficiency and compact design within automotive or industrial environments. Consider the input voltage range and output current requirements to ensure the device operates within its specified limits for optimal performance and thermal management.

Part Context

This part belongs to the LT3573 family of isolated flyback controllers from Analog Devices. These devices are engineered to simplify the design of isolated DC-DC converters by removing the opto-coupler, thereby enhancing system longevity and reducing size. The family includes various packages and temperature grades to suit different application constraints.
