Overview

Description

LT3755EUD-2#TRPBF is a dual synchronous buck controller from Analog Devices (Linear Technology). It drives two external N-channel MOSFETs to generate two regulated outputs from a single higher DC input, enabling compact dual-output power supplies.
Key points:
- Two independent (or cross-regulated) buck channels with current‑mode control.
- Programmable switching frequency, soft-start, enable/shutdown.
- Protections: UVLO/OVP, current limit, thermal shutdown.
- External components set output voltages; external MOSFETs handle the power stage.
- Suitable for telecom, industrial, and automotive front-end supplies requiring two rails.
Package and lot info:
- EUD is the package type; TRPBF indicates RoHS-compliant lead‑free, tape-and-reel packaging.
- The “-2” denotes a specific variant of the LT3755 in this package.
For exact electrical specs (input range, f_sw, output voltages, efficiency, currents), consult the LT3755 datasheet and product page.

Features

LT3755EUD-2#TRPBF features (typical):
- High-voltage, dual-channel constant-current LED driver/controller
- Wide input voltage range with high efficiency
- Buck/Boost operation for LED strings
- Two independently regulated LED currents (programmable via sense resistors; possible current balancing)
- Dimming support: PWM and analog dimming options
- Protection: open/short LED, overvoltage/UVLO, thermal shutdown, current limit
- Soft-start and robust fault protection
- Compact packaging (EUD variant) with Tape & Reel (TRPBF) availability; RoHS-compliant
Note: refer to the official datasheet for exact electrical specs and pinout.

Package

The LT3755EUD-2#TRPBF uses an 8-pin MSOP package (MSOP-8). Pb-free and provided in Tape & Reel (TRPBF).

Pinout

- Pin count: 28 pins (28-pin package).
- Function: Dual-channel high‑voltage constant‑current LED driver/controller with an integrated switching regulator, providing two independently regulated LED current channels (suitable for LED backlighting/dimming applications).

Manufacturer

Manufacturer: Analog Devices, Inc. (Linear Technology branding).
What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

Application

LT3755EUD-2#TRPBF is a high-efficiency, programmable constant-current LED driver. Typical application areas include:
- Automotive and general industrial lighting (constant-current LED driving)
- Display backlighting and architectural/signage lighting
- Street and outdoor LED lighting, MR16/high-power retrofit lamps
- Solar-powered or portable LED lighting systems
Note: Suitability depends on your specific LED string and input requirements.

Equivalent

LT3755EUD-2#TRPBF is Linear Technology’s high-voltage buck/boost LED-driver controller. There isn’t a direct one-for-one cross. Equivalents depend on your specs (input range, output current, topology, dimming). To find substitutes, use distributor cross-references and compare datasheet features. Likely candidate families include TI’s high-voltage buck/boost LED-driver controllers (e.g., LM5170/LM5172), ST’s LED-driver controllers, and Onsemi/NXP equivalents. Please share your target input/output specs for precise recommendations.
