LT3799EMSE#TRPBF

LED Driver IC Overview

The LT3799EMSE#TRPBF is an isolated flyback controller with active power factor correction, designed for driving LEDs. It operates as an AC/DC offline switcher supporting triac dimming. The device features a switching frequency range of 25 kHz to 300 kHz and delivers a single output. It functions within a supply voltage of up to 18 V with a quiescent current of 70 uA. The component supports adjustable output current and provides isolation. It is housed in a 16-MSOP package with exposed pad and operates between -40°C and +125°C junction temperature.

LED Driver IC Feature Summary

• Integrated active power factor correction for efficient line regulation
• Supports leading-edge and trailing-edge triac dimming compatibility
• Isolated flyback topology suitable for high-voltage LED applications

LED Driver IC Applications

• Offline isolated LED lighting systems
• Triac-dimmable LED drivers
• High-power factor LED ballasts

LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the order matches the exact part number to avoid confusion with non-reel variants or different temperature grades. Check RoHS compliance status via official documentation before procurement.

LED Driver IC Selection Notes

Select this component for designs requiring integrated PFC and dimming control in a compact surface-mount package. Consider the 16-MSOP footprint for PCB layout constraints. Evaluate the 300 kHz maximum switching frequency against thermal requirements. Verify input voltage ranges match the target AC line specifications.

LED Driver IC Part Context

This part belongs to the LT3799 series of isolated flyback controllers. It is specifically engineered for LED applications where power factor correction and dimming are critical. The series offers various package options and temperature grades to suit different manufacturing needs.

LED Driver IC Replacement Considerations

LT3799EMSE#PBF is a tube-packaged variant of the same functional device. LT3799IMSE#PBF represents the industrial temperature grade version. Verify pinout and electrical characteristics remain identical before substitution.
