概述

Description

LTM4620MPY is Analog Devices’ μModule (micro-power module) dual-output DC-DC buck regulator. It packs two synchronous buck converters, power MOSFETs, and an inductor into a single compact module, providing two programmable low-voltage rails from a higher input voltage.
Key points:
- Two independently adjustable outputs (VOUT1, VOUT2) with external feedback dividers.
- High efficiency via synchronous operation; suitable for dense power rails in CPUs, FPGAs, memory, etc.
- Features include remote sensing, sequencing options, soft-start, and protection (overcurrent/overtemperature/short-circuit).
- Optional digital control interface (PMBus/I2C) on some variants for monitoring and sequencing.
- MPY denotes a specific package variant of the LTM4620 family, designed for quick deployment with minimal external components; typically used with an evaluation board and reference designs.
In short: a compact, highly integrated dual-output power module ideal for modern VRMs and other tight-space power architectures.

Features

LTM4620MPY features (concise):
- Dual-channel multiphase µModule regulator with fully integrated inductor, power MOSFETs, and controller
- Wide input range and high efficiency for VRM-type applications
- PMBus-compatible digital interface for programming, telemetry, and fault reporting
- Programmable output voltages with remote sense and output sequencing
- Multiphase operation with phase interleaving for fast transient response
- Optional current sharing/parallel operation
- Protection: overcurrent/short-circuit, overvoltage, undervoltage, thermal shutdown
- Soft-start, enable control, and fault latch functionality
- Telemetry and fault reporting via PMBus
- Tiny MPY package for reduced board footprint; minimizes external components
- Suitable for CPUs, GPUs/FPGA, telecom, and industrial power rails
Note: See the datasheet for exact electrical specs, voltage ranges, and package details.

Package

The LTM4620MPY is supplied in an MPY μModule BGA package (a µModule/BGA module). For exact pin count, dimensions and land pattern, see the LTM4620 datasheet on the Analog Devices/Linear Technology website.

Pinout

Pin count: 25-ball BGA (MPY package).
Function: LTM4620MPY is a dual synchronous step‑down (buck) μModule DC/DC regulator that integrates controllers, MOSFETs, inductors and compensation to deliver two independent, adjustable outputs. Key pins/functions include VIN, GND, two VOUT pins, FB/RT/TRACK−SS, RUN/EN, SYNC, and power‑good/monitor signals. Typical use: compact, high‑efficiency regulation from a single input rail to two low‑voltage rails for point‑of‑load applications.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI).
What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits. It owns the Linear Technology line (LTM) and markets power-management modules.

Application

- High-end processor/GPU/FPGA/ASIC VRMs (point-of-load)
- Servers, data centers, workstations
- Networking, telecom, and storage equipment
- Industrial automation and motor-control systems
- Automotive electronics requiring compact, PMBus-enabled regulators
- Embedded/space-constrained applications needing multiple regulated rails
