Description
LT3680IMSE#TRPBF is Linear Technology/Analog Devices’ LT3680 LED driver in an MSOP-8 package. It is a high-voltage, constant-current LED driver with an integrated switching FET, designed to drive LEDs from a wide input range (up to about 60V) with high efficiency.
Key points:
- LED current sets via ISET resistor (and sense resistor), giving programmable constant current for one or more LEDs in series.
- Supports dimming (PWM and analog/DC) for brightness control.
- Includes protections: overcurrent, short-circuit, and thermal shutdown.
- Suitable for automotive lighting, backlighting, signage, and similar LED applications.
Packaging:
- IMSE = MSOP-8 package.
- TRPBF = Tape-and-reel, RoHS-compliant, Pb-free.
Application note:
- Typical circuit uses an inductor, a catch diode, a sense resistor, and an ISET resistor to define LED current.
For exact electrical specs, pinout, and application circuitry, refer to the LT3680 datasheet.
