Descripción general

Description

LT3680IMSE#TRPBF is the LT3680 DC-DC converter/controller in an IMSE package (MSOP with exposed pad) with tape-and-reel Pb-free packaging. The LT3680 is a high-voltage, high-efficiency dc-dc regulator that requires external passive components (inductor, diode or synchronous switch, sense/feedback resistors) and can be configured for buck, boost, or buck-boost applications depending on the surrounding circuitry. Key features typically include: wide input range, adjustable output, soft-start, enable/shutdown, current limit, and over-temperature protection. The “#TRPBF” suffix simply denotes the packaged tape-and-reel version that is Pb-free. For exact pinout, electrical specs, and reference circuit implementations, refer to the official datasheet and application notes.

Features

Here are the key features of the LT3680IMSE#TRPBF (Pb-free, Tape-and-Repair MSOP-8 variant):
- Dual synchronous buck regulator with integrated high-/low-side FETs
- Wide input voltage range suitable for automotive/industrial applications
- Two independently adjustable outputs (via feedback) with current-mode control
- Programmable switching frequency and/or synchronization options
- Enable input and Power-Good status output
- Soft-start to minimize inrush and output overshoot
- Comprehensive protection: overcurrent/short-circuit, undervoltage lockout, overvoltage protection, thermal shutdown
- High efficiency with fast transient response
- Small footprint in MSOP-8 package with exposed pad
- Pb-free, Tape-and-Reel packaging (TRPBF)
Note: For exact electrical specs (voltage ranges, currents, frequencies, and precise pinout), please consult the LT3680 datasheet.

Package

An MSOP-8 (3×3 mm) package. It’s Pb-free and comes on Tape & Reel (TR) packaging, as indicated by #TRPBF.

Pinout

Package: 10 pins (10-lead MSOP, suffix IMSE) plus exposed thermal pad.
Function (grouped, see datasheet for exact pin numbers and names):
- Power nodes: VIN (input supply), GND (ground/thermal pad), SW (switch/inductor node).
- Gate-drive: BOOST/ BST (bootstrap supply for internal switch).
- Regulation/control: FB (feedback), COMP (error‑amp/loop compensation).
- Control/interface: RUN/EN (enable/shutdown), MODE/SYNC (mode selection and/or external sync).
- Remaining pin(s): device-specific functions or NC.
For the precise pin‑number assignment and electrical details, consult the LT3680 datasheet.
