Murata Power Solutions MPQ1800 & MPQ2000N Quarter-Brick DC-DC Converters

Murata Power Solutions MPQ1800 and MPQ2000N Quarter-Brick DC-DC Converters feature regulated 12V rails from 40VDC to 60VDC inputs. Murata MPQ1800/2000N DC-DC Converters share a 58.4mm L x 36.8mm W x 14.7mm H footprint. The MPQ2000N features a non-isolated 2000W, 167A output with up to 97.9% peak efficiency. The MPQ1800 integrates 700VDC isolation and delivers 1800W, 150A with up to 97.5% peak efficiency. Designed for digitally managed power systems, both devices offer PMBus 1.2 interfaces, active current sharing, event logging, baseplate thermal management, and integrated voltage, current, and temperature protections.
