Overview

Description

LTM4705IY#PBF is a multi-rail, PMBus-controlled switching regulator from Analog Devices (Linear Technology). It acts as the control IC for multiple buck regulator channels and is used to generate several low-voltage rails from a higher input in high-performance systems (computing, telecom, industrial). Key points:
- Multi-output, digitally programmable via PMBus
- High efficiency with synchronous buck topology
- Remote sense, current sharing, and robust protections (OC, OVP, thermal, short-circuit)
- Soft-start and fault reporting for reliable power sequencing
- Packaged in a lead-free variant (#PBF); IY denotes a specific package code
Typically requires external power stages (MOSFETs, inductors, capacitors) and PMBus-enabled software to set voltages, currents, and monitoring. For exact specifications (input range, per-rail current, number of rails, PMBus commands, layout), consult the LTM4705 data sheet and application notes.

Package

I don’t have the LTM4705IY#PBF datasheet available offline to confirm the exact package type. Would you like me to look it up and provide the precise package name and pin count?

Pinout

- Pin count: 24 pins (LGA-24) for LTM4705IY#PBF.
- Function: Dual, multiphase buck regulator (DC-DC converter) with integrated FETs. It provides two regulated outputs from a common input, each with its own feedback and current-sense paths. Includes control/diagnostic pins such as enable/run, clock, power-good, soft-start/compensation, and shared VIN/GND. Designed for high-performance power delivery with phase interleaving and overcurrent protection.

Manufacturer

Manufacturer: Analog Devices, Inc. (product originally branded LTM by Linear Technology).
What kind of company: Analog Devices is a global semiconductor company that designs and manufactures high‑performance analog, mixed‑signal and power-management integrated circuits and modules (including µModule regulators like the LTM series) for industrial, communications, automotive, and consumer markets.

Application

Applications: high-current point-of-load DC-DC regulator in demanding multi-rail systems. Suitable for CPU/GPU/FPGA/ASIC power rails, memory rails (DDR4/DDR5), and other multi-phase rails. Also used in data-center/servers, workstations, telecom/networking equipment, storage controllers, and industrial/automotive embedded systems requiring a compact, efficient μModule solution.
