Overview

Description

LT3751EFE#TRPBF is the lead‑free, tape‑and‑reel variant of Linear Technology/Analog Devices' LT3751 high‑voltage LED driver controller. It’s a wide‑input, current‑mode DC‑DC controller designed to drive constant‑current LED strings from a high input voltage using a switching regulator (buck, boost, or buck–boost topology as configured in the application). The LED current is set with an external sense resistor and fed back to regulate current independently of LED forward voltage. Key features typically include: adjustable LED current, PWM dimming, soft‑start, overcurrent/short‑circuit protection, undervoltage/overvoltage protection, and thermal protection. The EFE suffix indicates the specific package/temperature variant, while TRPBF denotes Tape‑and‑Reel packaging with Pb‑free construction. Typical applications: LED backlighting for LCDs, signage, automotive lighting, and general high‑brightness LED lighting. For exact electrical specs, operating ranges, and pinout, consult the LT3751 datasheet and application notes.

Package

LT3751EFE#TRPBF is a 16‑lead TSSOP (Pb‑free) package, supplied in Tape & Reel.

Pinout

- Pin count: 16 pins (MSOP-16/SO-16 package variants; TRPBF indicates Tape&Reel, Pb-free).
- Function: High‑voltage buck/boost LED driver/controller with an integrated switching MOSFET for constant‑current LED string driving; regulates current via a sense resistor and includes feedback, enable/diagnostic, and related control pins.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LT prefix originally comes from Linear Technology, which was acquired by Analog Devices in 2017.
- What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits, including power management and signal-processing ICs.

Application

Typical applications for LT3751EFE#TRPBF include:
- Offline AC-DC and telecom/industrial power supplies (isolated or non-isolated)
- Automotive and other high-voltage DC-DC converters
- LED backlight and lighting driver systems (constant-current)
- Battery charging and overall power-management circuits
- Solar/energy-harvesting regulator topologies
