概述

Description

The LTM4633MPY is a triple-output, high-efficiency point-of-load (POL) DC–DC regulator in an Analog Devices (formerly Linear Technology) μModule package. It integrates three synchronous buck regulators on a single compact module to generate three rails from a common input, delivering fast transient response and tight regulation for processors, FPGAs, and other high-performance loads.
Key features (typical):
- Three independently adjustable outputs from one input
- Compact μModule package (MPY)
- Remote sensing, sequencing, and monitoring
- Telemetry for voltage/current/temperature
- Protection features (overcurrent, overtemperature, undervoltage/short-circuit)
- Suitable for wide input ranges and high-efficiency power delivery
Common uses include multi-rail power delivery for CPUs/GPUs, ASICs, DSPs, and other high-density electronics boards. For exact electrical specs, pinout, and programming, consult the latest LTM4633MPY datasheet.

Features

- Three-channel µModule buck regulator with PMBus digital control
- Fully integrated: power FETs, inductor, driver, and compensation network
- PMBus interface for voltage setpoints, readback, sequencing, and alerts
- Per-channel adjustable outputs with remote sense and load-line compensation
- Wide input voltage range suitable for VRMs
- High efficiency with synchronous rectification
- Built-in protections: overcurrent/short-circuit, overtemperature, undervoltage lockout
- Power-good signaling, fault reporting, and programmable sequencing/tracking
- Compact MPY package (no external magnetics required) suited for dense power layouts
Note: For exact electrical specs (voltage ranges, current capacity per channel, switching frequency), refer to the LTM4633MPY datasheet.

Package

The LTM4633MPY is supplied in Analog Devices’ MPY μModule package — a compact BGA-style μModule power package. For exact dimensions, ball count, and land pattern, see the LTM4633 datasheet.

Pinout

Pin count: 28 pins (LGA/µModule package, MPY variant).
Function: LTM4633MPY is a triple-output PMBus-enabled DC-DC converter µModule. It contains three independent buck regulators fed from a common input, providing three programmable outputs with individual feedback. It includes PMBus/ SMBus control pins (SCL/SDA, address), enable/run, PGOOD, and fault/alert lines, plus Vin and GND. Designed for compact point-of-load regulation with integrated power stage, regulation, and protection.

Manufacturer

Manufacturer: Analog Devices, Inc. (ADI). The LTM4633MPY is part of ADI’s μModule regulator family (originally Linear Technology). Analog Devices is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits and related system solutions.

Application

Applications include high‑density, multi‑rail power for digital systems:
- Servers and data centers (CPU/GPU/FPGA core rails)
- Networking/telecom equipment
- Storage controllers and NVMe devices
- Industrial automation and robotics
- Medical devices and diagnostic equipment
- Test/measurement equipment
Ideal for compact, efficient multi‑output power delivery from a single module.
