Visão Geral
Description
LTM4633MPY is a triple-output μModule DC-DC regulator from Analog Devices (Linear Technology family). It packs three high‑current buck regulators, control logic, and passive components into a single compact module. A common input feeds three independently programmable outputs (V1, V2, V3), ideal for multi‑rail power architectures. It supports PMBus/I2C for setup and telemetry (voltage, current, temperature, faults) and includes protections such as overcurrent and over‑temperature with fault reporting. Key benefits include high efficiency, fast transient response, remote sensing options, and simplified board integration due to its self-contained package. It’s well suited for powering core rails in FPGAs, CPUs, ASICs, and other high‑performance digital systems, reducing BOM and layout complexity.
Equivalent
There is no single exact, pin‑for‑pin equivalent to Analog Devices’ LTM4633MPY. Closest alternatives are other μModule DC‑DC regulators with the same VIN/VOUT range, current rating and footprint—e.g., other ADI LTM family modules, TI’s TPSM power‑module series, and Murata/RECOM DC‑DC power modules. Use a parametric search (VIN, VOUT, IOUT, footprint, switching frequency) to find the best match.
Pinout
- Pin count: 28 pins (LGA/MPY package).
- Function: PMBus-enabled triple-output multiphase synchronous buck regulator power module. Integrates controller, high-side/low-side MOSFETs and drivers to generate three regulated rails from a common input, with PMBus/SMBus interface for voltage, enable, monitoring and fault reporting.
