SSQE48T25033 Series

The new SSQE48T25033 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 25 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 SSQE48T25033 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.
