LED Driver IC Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the manufacturer is Analog Devices Inc., as the product was previously associated with Linear Technology. Ensure compatibility with the 16-MSOP-EP footprint during PCB layout. Check for any recent production lifecycle notices or obsolescence warnings from the distributor before finalizing procurement plans.

LED Driver IC Selection Notes

Select this component for designs requiring integrated PFC in an isolated topology. The 300 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 10 V output limit when designing transformer turns ratios. The wide operating temperature range suits industrial environments. Verify input voltage ranges against specific application requirements not detailed in the summary.

LED Driver IC Part Context

This part belongs to the LT3799-1 series, which are specialized controllers for LED applications. It differs from standard flyback controllers by including dedicated PFC circuitry. The EMSE-1 designation specifies the MSOP package and temperature grade. The TRPBF suffix denotes the specific reel packaging format for automated assembly processes.

LED Driver IC Replacement Considerations

LT3799IMSE-1#TRPBF is a confirmed substitute offering identical functionality with potential industrial temperature grade variations. LT3799EMSE#TRPBF serves as a related variant within the same family. Verify pinout compatibility and thermal performance when substituting across different package suffixes or temperature grades.
