Overview

Description

LTM2881IY-5 is a Linear/Analog Devices LTM µModule DC-DC converter. It is a highly integrated, fixed-output power module that combines a switching regulator, power MOSFETs, inductor, and essential passives in a single compact package.
Key points:
- Fixed 5V output version (the -5 suffix denotes 5V output).
- Fully integrated: minimal external components beyond input/output caps.
- Built-in protections: overcurrent/short-circuit, overtemperature, undervoltage protection, and soft-start; includes enable and power-good signaling.
- High efficiency and fast transient response; suitable for point‑of‑load power near processors, FPGAs, and DSPs.
- Small footprint and SMT package for board-level integration.
- Typical use: compact, rugged supply in space-constrained, mixed-signal or embedded systems.
For exact electrical specifications (Vin range, Iout, efficiency, pinout, layout recommendations), refer to the LTM2881IY-5 datasheet and product page.

Features

Here are the typical features of the LTM2881IY-5 (µModule isolated DC-DC converter family). Exact numbers depend on the revision, so verify with the datasheet.
- Isolated µModule DC-DC converter
- Fixed 5 V output
- Output current capability around 1 A (typical)
- galvanic isolation between input and output
- Fully integrated: transformer/inductor, switches, controller (no external components)
- High efficiency and compact packaging
- Wide input voltage range
- Protection: overcurrent/short‑circuit, over/under-voltage, over‑temperature
- Remote on/off control option
- Industrial temperature range (-40°C to ~125°C, depending on variant)
- RoHS compliant
For exact electrical specs (input range, exact current rating, isolation voltage, efficiency, and pin/package details) please consult the latest datasheet.

Package

The LTM2881IY-5 uses a μModule (LTM) package — an encapsulated, self-contained module (not a standard discrete IC).

Pinout

LTM2881IY-5 is a 16-pin μModule package. Its function is to provide a galvanically isolated SPI interface (isolated data lines) between a host controller and a target device, with separate supply rails on the two sides (host side and isolated side).

Manufacturer

Manufacturer: Analog Devices, Inc. (the LTM line originated with Linear Technology and is now part of Analog Devices).
What kind of company: A global semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs and systems (including power management, data converters, sensors, and related solutions).

Application

- Isolated digital interfaces (SPI/I2C/UART) between low-voltage controllers and high-voltage/noisy domains
- Industrial automation and process control (sensors, actuators, PLCs)
- Data acquisition and instrumentation in mixed-voltage systems
- Power electronics and motor-drive applications requiring galvanic isolation
- Medical devices requiring isolation (subject to regulatory certification) for patient safety

Equivalent

Equivalent products to LTM2881IY-5 are other isolated SPI interface devices. Common cross-refs include:
- Analog Devices ADuM1250/1251/1252 (isoSPI isolators)
- Texas Instruments ISO1540/ISO1541 (isoSPI isolators)
- Silicon Labs Si86xx / Si862x (isoSPI isolators)
Some vendors offer integrated isolated-regulator variants in the same family. For exact pinout and regulator options, check the vendor cross-reference tool.
