Description

The LTM4651IY#PBF is a μModule DC-DC regulator from Analog Devices (formerly Linear Technology). It’s a highly integrated power module that combines the regulator controller, power MOSFETs, and typically an inductor and supporting components in one compact package to convert a higher input voltage to a regulated output for VRMs and similar loads. Features usually include enable, output tracking/soft-start, remote sense, power-good, over‑voltage protection, current limit, and good transient response. The IY suffix indicates a specific package variant, while #PBF denotes Pb-free, RoHS-compliant (lead-free) packaging, typically tape-and-reel. Use it to simplify high-current voltage regulation for CPUs, GPUs, FPGAs, and other demanding digital systems. For exact specifications (input range, output voltages, efficiency, pinout), consult the LTM4651IY#PBF datasheet and reference designs.

Features

Key features of LTM4651IY#PBF:

- Enable/shutdown control and soft-start
- Sequencing and margining capabilities; Power-Good signaling
- Fault reporting with robust protection: overcurrent/short-circuit, overvoltage, overtemperature, UVLO
- High efficiency suitable for VRMs; wide input voltage range
- RoHS-compliant packaging (IY), compact footprint
- Operating temperature typical for rugged applications (-40°C to 125°C)
- Applications: CPU/GPU memory VRMs, data-center/telecom power rails, embedded systems
Note: for exact voltage ranges, timing, and electrical specs, please consult the latest datasheet.

Package

LTM4651IY#PBF is supplied in a µModule ball‑grid array (BGA) package (lead‑free, #PBF). For exact ball count and dimensions, see the LTM4651 datasheet.

Pinout

- Pin count: 16 pins (4x4 mm µModule package)
- Function: Dual synchronous buck regulator µModule; two independent buck regulators with integrated power components (MOSFETs, inductor), used to generate two low-voltage rails from a higher input.

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI). The LTM4651IY#PBF is from Linear Technology’s LTM μModule regulator family, now part of Analog Devices after the acquisition.
