C&D Technologies VR091B080CS Voltage Regulator Module

The VR091B080CS is a Murata Power Solutions voltage regulator module (VRM) in the C&D Technologies lineage, delivering up to 80 A of programmable, single‑output DC‑DC regulation in a compact 3.8" L x 2.3" H x 0.57" W package, designed for CPU power and other high‑density power rails. It runs from a nominal 12 V input (min about 11.04 V, max about 12.60 V) and outputs a programmable voltage from 1.075 to 1.85 V via a 5‑bit DAC, using a multi‑phase buck topology for tight regulation. The module includes remote sense, remote enable, and a Power Good output, plus protections such as output over‑voltage latch‑off and over‑current/short‑circuit protection, with RoHS‑compliant variants like VR091B080CS‑1C. Suitable for CPU cores, GPUs, and other high‑performance digital devices, this VRM enables precise voltage control and compensation for trace drops on complex boards.
