概述

Description

Introduction to LTM2881CV-3#PBF
- LTM2881CV-3#PBF is a Linear Technology (now Analog Devices) LTM family μModule device. It provides isolated power and a compact, integrated interface to control that isolated supply in a single module.
- The “CV-3” portion denotes a specific variant/voltage/package option within the LTM2881 family; “#PBF” indicates Pb-free, lead-free packaging (typically tape-and-reel).
- Applications: used to power and communicate with remote subsystems in industrial, telecom, medical, or instrumentation equipment while maintaining galvanic isolation.
- Benefits: small size, integrated regulation and isolation, simplified board-level design, and compatibility with system isolation requirements.
- Important: for exact electrical specs (input/output ranges, isolation voltage, communication protocol, thermal limits), consult the official LTM2881 datasheet and product page.

Features

Here are the typical features of the LTM2881CV-3#PBF (Pb-free) μModule isolated DC-DC converter:
- Galvanic isolation between input and output
- Integrated high-efficiency switch-mode regulator in a compact μModule package
- Wide input voltage range (typical for LTM µModule family)
- Fixed 3.3 V output version (indicated by the “-3” suffix)
- High power density and small footprint
- Tight output regulation with protection features
- Overcurrent/short-circuit protection
- Overvoltage protection and undervoltage lockout
- Thermal shutdown protection
- Pb-free (PBF) packaging; RoHS compliant
- Industrial operating temperature range (typical)
Note: For exact electrical specs (Vin range, efficiency, current capability, regulation tolerance, etc.), please consult the current datasheet.

Package

Package type: Pb-free LGA (land grid array) package.

Pinout

Pin count: 20 pins.
Function: LTM2881CV-3#PBF is a 20‑pin μModule isolated DC‑DC converter. It provides galvanic isolation between input and output and includes the regulator, transformer, and control circuitry. Pins cover input side (VIN/GND), isolated output (VOUT/GND, VISO), feedback, enable/shutdown, and status/diagnostic signals. For exact pinout and per‑pin functions, refer to the LTM2881 data sheet and package CV-3/PBF variant details.

Manufacturer

Analog Devices, Inc. (ADI). ADI is a multinational semiconductor company that designs and manufactures analog, mixed-signal, RF, and digital signal processing integrated circuits, including μModule regulators under the LTM brand.

Application

Application areas of LTM2881CV-3#PBF:
- Galvanic isolation between host and remote/high-voltage domains
- Isolated power supplies for MCUs/FPGA, sensors, and data converters
- Isolated digital interfaces (I/O, serial links) in industrial automation
- Automotive, medical, and telecom equipment needing safety isolation and EMI control
- Distributed control systems and power architectures with isolation requirements

Equivalent

LTM2881CV-3#PBF is a µModule isolated SPI interface. Direct cross‑reference depends on your specs (voltage rails, isolation voltage, speed, package). Functionally similar parts include:
