LT3798EMSE#TRPBF

AC DC Converters, Offline Switchers Overview

The LT3798EMSE#TRPBF is an isolated flyback controller integrating active power factor correction (PFC) with no opto-coupler feedback. It operates from a 10V to 38V supply, supporting switching frequencies between 500Hz and 150kHz. The device provides constant-voltage/constant-current regulation for outputs up to 80W typical power. It features a 20ns rise/fall time and functions within a -40°C to +125°C temperature range in an MSOP-16 package.

AC DC Converters, Offline Switchers Feature Summary

• Integrates active PFC with isolated flyback control
• Eliminates need for opto-couplers via primary-side regulation
• Supports wide input voltage supply range
• Enables high-efficiency LED driver applications

AC DC Converters, Offline Switchers Applications

AC DC Converters, Offline Switchers Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and lot traceability prior to integration. Ensure storage conditions maintain moisture sensitivity level integrity. Validate datasheet revision matches procurement documentation to avoid functional discrepancies in final assembly processes.

AC DC Converters, Offline Switchers Selection Notes

Select this controller for designs requiring simultaneous PFC and isolated regulation without opto-isolation complexity. Suitable for medium-power applications up to 80W where efficiency and component count reduction are priorities. Consider thermal management due to MSOP-16 package constraints. Verify input voltage range compatibility with system architecture before implementation.

AC DC Converters, Offline Switchers Part Context

Part of the LT3798 family of isolated flyback controllers. Designed by Analog Devices for high-performance power conversion. Shares architectural similarities with other primary-side regulated controllers but distinguishes itself through integrated PFC functionality. Commonly used in commercial and industrial power supply designs requiring strict regulatory compliance.

AC DC Converters, Offline Switchers Replacement Considerations

LT3798EMSE#PBF is the tube-packaged equivalent of the same functional device. LT3798EMSE#TR is the reel-packaged variant without Pb-free suffix specification. No direct cross-manufacturer substitutes are officially documented; design adaptation required for alternative ICs.
