概述
Description
LT3995IMSE#TRPBF is Linear Technology’s LT3995 LED driver IC, sold in the MSOP-style package designated by the IMSE code. The suffix #TRPBF means Tape-and-Reel packaging that is Pb-free.
What it is:
- An LED driver designed to regulate current through one or more LED strings with protection features and dimming options.
Packaging/ordering details:
- IMSE = MSOP-style (package type, 8-pin in this case; check the datasheet for exact pinout).
- TRPBF = Tape-and-Reload (Tape & Reel) Pb-free packaging.
Where to look next:
- See the LT3995 datasheet for full electrical specs, pinout, input/output ranges, current settings, dimming methods, and application notes. The Analog Devices website lists exact packaging diagrams and ordering information.
