Up to 30W output power @ 36 – 48 – 75Vin
89% efficiency (typical, 5Vout)
PRODUCT OVERVIEW
Through-hole and optional SMT package
The ULT Series isolated DC/DC converter repre-
sents the next generation converters in a 1/32
brick package. This converter is the “industry-
standard” 1/32 brick form factor (0.92" x 0.75"
x 0.35"). The product fully complies with RoHS-6
directive.
The thirty-second brick is offered as an open
frame module; mounting options include through-
hole or surface mount (SMT) pinouts. Typical
applications include Optical Networking Equipment, standard 1/32 brick.
Wireless Base Station applications, Microwave
Radio communications, and Telecom and Data
Equipment applications.
Modules will supply an output power of up to
30 watts over the input range of 36-75V. The ULT
Series also provides a cost effective approach to
highly efficient systems requiring 12V, 5V, and 3.3V
voltages, eliminating the requirement for a “Bus
Converter” and multiple PoL converters. The ULT
family provides basic insulation with 1500Vdc iso-
lation meeting the requirements of EN60950. The
ULT series modules are DOSA compatible industry
