描述 Description

The MCOTS-B-270-31-HT bus converter is a nextgeneration, board-mountable, isolated, fixed switching frequency DC-DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The MCOTS series provides an isolated step down voltage from 270 V to 31 V intermediate bus with no regulation in a standard half-brick module. The MCOTS-B-270-31-HT converter is ideal for creating the mid-bus voltage required to drive standard 31 V DC-DC isolated converters.
