LTC3676EUJ#TRPBF

LTC3676EUJ#TRPBF is a high‑current, multiphase buck regulator IC from Linear Technology (now Analog Devices). It combines a multi‑phase buck controller with drivers and high‑side FETs to generate stable, high‑quality CPU/memory rails and other demanding power rails.
Key points:
- Multiphase operation (2‑ or 3‑phase) for high current with good transient response.
- Wide input range, programmable output voltage, and adjustable switching frequency.
- Current‑mode control with cycle‑by‑cycle current limit, soft‑start, and enable.
- Remote sensing, fault protection (overcurrent/overtemperature/UVLO), and protection features suitable for digital loads.
- Integrates drive outputs for the high‑side FETs.
Package/ordering:
- EUJ denotes the package code; TRPBF indicates Tape & Reel, Pb‑free version.
Typical use:
- CPU/GPU core supplies, memory rails, FPGAs, and other high‑efficiency, high‑current DC‑DC power needs.
For exact electrical specs, pinout, and application notes, refer to the LTC3676 datasheet.

Direct pin-for-pin equivalents for LTC3676EUJ#TRPBF don’t exist; it’s a dual/multi‑phase DC‑DC controller with external FET drive. To replace it, look for a similar dual synchronous buck controller with multiphase support from TI, Analog Devices, Maxim, etc. For a precise cross‑reference, provide: required input/output ranges, number of phases, package, and any critical features, or allow me to search distributors for an exact match.

- Pin count: 32 pins (EUJ package)
- Function: Dual synchronous buck-boost regulator controller (two independent regulator channels with gate-drive capability for external MOSFETs).

- Manufacturer: Analog Devices, Inc. (the LTC prefix indicates Linear Technology; Linear Technology was acquired by Analog Devices in 2017).
- What kind of company: A multinational American semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits.

Typical application areas for the LTC3676EUJ#TRPBF include:
- Automotive power management (ECUs, infotainment, battery/rail regulation)
- Industrial automation and motor-control DC-DC supplies
- Telecom/network equipment DC-DC rails
- Solar/battery-powered systems and energy-harvesting back-ups
- Portable/battery-powered devices
- Distributed power for FPGAs/CPUs in data centers
It’s used where a high-efficiency dual-channel DC-DC conversion (buck/boost) with wide input range is needed.

LTC3676EUJ#TRPBF comes in a 28‑lead QFN package (4×4 mm) with an exposed pad. TRPBF indicates Tape‑and‑Reel, RoHS (Pb‑free) packaging.
