概述

Description

The LTM4633MPY#PBF is a high-density, triple-output DC-DC switcher in Linear Technology/Analog Devices’ µModule (MPY) package. It integrates three switching regulators, control logic, and passive components in one compact module to generate three rails from a single input with high efficiency and fast transient response. It uses a PMBus digital interface for programming output voltages and for telemetry (VIN, VOUT, IOUT, temperature) and fault reporting.
The MPY package provides a drop-in, surface-mount solution with integrated inductors/MOSFETs; external parts are mainly input/output filtering and decoupling. The #PBF suffix indicates Pb-free, RoHS-compliant packaging.
Typical uses include CPU/GPU cores, FPGAs, and other high-current digital loads requiring multiple regulated rails with simple board integration. For exact electrical specs, pinout, efficiency, and PMBus commands, consult the LTM4633 datasheet and PMBus guide.

Package

28-pin Plastic Quad Flat Package (LQFP), RoHS lead-free (PBF).

Manufacturer

Manufacturer: Analog Devices, Inc. (originally a Linear Technology product — LTM series µModule).
What kind of company: Analog Devices is a semiconductor company that designs and manufactures analog, mixed-signal and power-management integrated circuits and complete µModule power solutions used in industrial, communications, automotive and consumer electronics.

Application

Applications of LTM4633MPY#PBF (multi-output, high‑current PMIC):
- Server/datacenter VRMs (CPU/GPU cores, memory, I/O)
- FPGA/ASIC/DSP power delivery
- Networking/telecom gear (switches, base stations)
- Industrial automation and motor-control rails
- Embedded/AI edge devices needing compact, high‑current regulators
- Test equipment and lab power supplies with multiple rails
A compact, high-efficiency multi-rail solution for space-constrained environments.

Equivalent

I can’t reliably look up parts right now, but there are no guaranteed pin‑for‑pin drop‑in equivalents to the LTM4633MPY#PBF. Use the same LTM4633 family variant or choose a functionally equivalent µModule regulator (matching VIN, VOUT, max load, footprint and thermal specs) from Analog Devices, TI (TPSM series) or Murata. For a confirmed replacement, check ADI’s cross‑reference or distributor listings (Digi‑Key, Mouser) or contact ADI support.
