DC-DC Converter
The InQor® quarter-brick converter series is composed
of next-generation, board-mountable, isolated,
fixed switching frequency dc-dc converters that use
synchronous rectification to achieve extremely high
power conversion efficiency. Each module is supplied
completely encased to provide protection from the
harsh environments seen in many industrial and
transportation applications.
