Description
LTM4643IV#PBF is Analog Devices’ LTM4643 µModule regulator in Pb-free packaging (PBF), variant IV. It’s a highly integrated, three-channel (multi-rail) synchronous DC-DC converter with PMBus digital control in a single compact module. The device combines three buck regulators, power MOSFETs, inductors/capacitors, and the control logic, enabling multiple low-voltage outputs from a common input rail.
Key features (typical): PMBus interface for programing and monitoring, remote sense, voltage tracking/margining, current sharing and overcurrent/thermal protection, and efficient operation across a wide input range (system commonly 4.5–15 V, with outputs set to low rails suitable for CPUs, memory, etc.).
Applications: multi-rail VRMs for processors, memory, graphics, high-performance computing, telecom and servers.
Note: IV designates the packaging variant; PBF confirms Pb-free. For exact rail voltages, current capability, pinout, and electrical characteristics, consult the LTM4643 datasheet and product documentation.

Equivalent
To give accurate equivalents, please specify:
- Do you want pin‑compatible drop-ins or functionally similar (non‑pin‑compatible) parts?
- Your required specs: input/output voltages, current, package, temperature range.
I can then fetch current cross‑refs from major vendors (TI, OnSemi, Infineon, etc.).

Pinout
The LTM4643IV#PBF is supplied in a 48-pin (48-ball) BGA μModule package. It is a 4‑phase synchronous step‑down DC/DC μModule regulator (complete point‑of‑load power solution) that integrates controllers, power MOSFETs and inductors to deliver high‑current, adjustable output(s). (#PBF denotes Pb‑free.)
Manufacturer
The LTM4643IV#PBF is from Linear Technology (now part of Analog Devices, Inc.). Linear Technology/Analog Devices is a global semiconductor company that designs and manufactures analog and mixed‑signal integrated circuits, specialty power-management products (including µModule DC/DC regulators like the LTM series), data converters, amplifiers, and related components for industrial, communications, automotive, and consumer markets.
Application
LTM4643IV#PBF is a high‑current, multi‑phase DC–DC µModule regulator. Typical application areas:
- Data centers and servers: CPU/GPU/ASIC power rails, high‑current VRMs
- High‑performance computing: motherboards, FPGA/SoC power management
- Networking/telecom: switches, routers, base stations requiring multiple regulated rails
- Industrial automation and control systems needing multiple, tight‑tolerance supplies
- Edge and AI acceleration systems with demanding, fast transient responses
Suitable for any design needing compact, efficient, multi‑rail power from a single 12V/nominal input.
