The new SSQE48T07050 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 7 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 SSQE48T07050 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.
