Overview

Description

LT3680EMSE#TRPBF is the Linear Technology (now Analog Devices) LT3680 LED-driver/DC-DC converter in the EMSE package. The #TRPBF suffix means Tape-and-Reel, Pb-Free packaging; EMSE designates the specific package variant (an MSOP-8/DFN-8 style).
Key points:
- It’s a high-efficiency switching regulator designed to drive LED strings with constant current (supports buck/boost/buck-boost topologies using an external inductor and sense resistor).
- Internal high-side switch + current-sense/comparator enable precise LED current; includes dimming options (PWM or analog/dc control), soft-start, and protections.
- You set LED current with a sense resistor; requires external components per datasheet.
- Suitable for automotive, backlighting, and general lighting applications.
For exact electrical specs (input range, LED current, switching frequency, dimming details), consult the LT3680 datasheet and the EMI/packaging note for EMSE/TRPBF variants.

Features

Key features of LT3680EMSE#TRPBF (EMSE package, Tape & Reel, Pb-free) include:
- Wide input range up to 42V
- Buck regulator with integrated high-side switch
- Adjustable output via external resistors
- Current-mode control for fast transient response
- Synchronous rectification
- Adjustable switching frequency
- Soft-start and enable/shutdown control
- Protections: overcurrent/short-circuit, overvoltage, undervoltage lockout
- Thermal shutdown/thermal protection
- Remote sense capability
- External compensation options for loop stability
- Pb-free, packaged in EMSE (MSOP-type) with TRPBF tape & reel
Note: Exact output current capability and switching frequency range depend on the specific device variant.

Package

LT3680EMSE#TRPBF uses an MSOP-8 package with an exposed pad (MSOP-8 EP). It is Pb-free and shipped in Tape & Reel packaging (TRPBF).

Pinout

- Pin count: 8 pins in an MSOP-8 package (LT3680EMSE; with exposed pad).
- Function: High-efficiency buck DC-DC regulator/controller. Uses an external inductor to regulate a higher input voltage down to a lower output; provides control pins for feedback, enable/shutdown, and switch node (LX) to drive the external FETs.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LT prefix originally comes from Linear Technology, which ADI acquired in 2017.
- Company type: An American multinational semiconductor company that designs, develops, manufactures, and markets analog, mixed-signal, and DSP integrated circuits.

Application

LT3680EMSE#TRPBF is a high-efficiency DC-DC buck regulator. Typical applications include:
- Portable and battery-powered devices (long battery life)
- Point-of-load regulation for CPUs/SoCs and other ICs
- Automotive and industrial power management (wide input range)
- Telecom/network equipment rails
- LED backlight/high-efficiency DC-DC power supplies
(“EMSE#TRPBF” mainly denotes package and Pb-free tape-and-reel options.)
