ULT Series

Thirty-Second-Brick Isolated DC/DC Converters

with 2:1 Wide Input Range

FEATURES



2:1 Input Voltage Range (36V – 75V, 48 Volts,

Typical units

nominal)



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,

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 UL/IEC 60950.

The ULT series modules are DOSA compatible

industry standard 1/32 brick.

Miniature 1/32 brick open frame package



Positive & Negative Logic On/Off control option



Over-current & Over-temperature protection



Low output ripple and noise



Strong thermal derating characteristics



Operational Temperature Range –40°C to +85°C



1500V I/O isolation



Tight line/load regulation



Certiﬁed to UL/IEC 60950-1, CAN/CSA C22.2 No.
