Description
The new SSQE48T20033 DC-DC converter is an open frame sixteenth-brick DC-DC converter that conforms to
the Distributed Open Standards Architecture (DOSA) specifications. The converter operates over an input voltage
range of 36 to 75 VDC, and provides a tightly regulated output voltage with an output current up to 20 A. The
output is fully isolated from the input and the converter meets Basic Insulation requirements permitting a positive
or negative output configuration.
The converter is constructed using a single-board approach with both planar and discrete magnetics. The
standard feature set includes remote On/Off (positive or negative logic), input undervoltage lockout, output
overvoltage, overcurrent, and short circuit protections, output voltage trim, and overtemperature shutdown with
hysteresis.
With standard pinout and trim equations and excellent thermal performance, the SSQE48T20033 converters can
replace in most cases existing eighth-brick converters. Inclusion of this converter in a new design can result in
significant board space and cost savings.
