概述

Description

LTM4662EY#PBF is a Linear Technology (Analog Devices) µModule dual-channel, multiphase buck regulator. It is a fully integrated DC–DC converter (controller, power MOSFETs, and often an inductor) in a compact μModule package, designed for high-current point-of-load supplies. External components are minimal (input/output capacitors and a feedback network); some versions offer digital control via PMBus.
The EY package denotes the specific mechanical footprint, while #PBF indicates Pb-free packaging (tape-and-reel). Typical use cases include VRMs for CPUs/GPUs, FPGAs, and telecom/server power rails.
Key features usually include:
- Dual interleaved/multiphase buck channels
- Wide input range and adjustable outputs
- High efficiency and fast transient response
- Protective functions (overcurrent, overvoltage, thermal shutdown)
- Enable/soft-start and, in some variants, remote sensing or digital control
For exact electrical specs, pinout, and application circuits, refer to the LTM4662 datasheet and evaluation board.

Package

Pb-free LQFN package, 24 pins (approximately 4×6 mm).

Pinout

- Pin count: 28 pins (LGA package).
- Function: Dual μModule DC-DC regulator (two synchronous buck regulators) with integrated inductor, such that two independently adjustable outputs are generated from a common input; PMBus-compatible digital control.

Manufacturer

Analog Devices, Inc. (ADI). It is a multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits. ADI acquired Linear Technology in 2017, which originally developed the LTM μModule product family.

Application

- CPU/GPU VRMs and other high‑current point‑of‑load regulators
- Server, data‑center, and telecom/network power rails
- Front‑end hot‑swap and redundant/OR‑ing power supplies
- Industrial automation and motor‑control power paths
- Automotive and battery‑powered systems with high‑voltage inputs
