UEI30 Series  
s
30W Isolated Wide-Range DC-DC Converters  
Featuring a full 30 Watt output in 1.8 square inches of board area, the UEI  
series isolated DC/DC converter family offers efficient regulated DC  
power for printed circuit board mounting.  
Typical unit  
FEATURES  
PRODUCT OVERVIEW  
  
Small footprint DC/DC converter, ideal for high  
current applications  
Wide range 4:1 inputs on the 0.92" x 1.92" x 0.35"  
converter are either 9 to 36 Volts DC (Q12 models)  
or 18 to 75 Volts DC (Q48 models), ideal for  
battery-powered and telecom equipment. Fixed  
output voltages from 3.3 VDC to 15 VDC are tightly  
regulated and may be trimmed within 10ꢀ  
of nominal output. Applications include small  
instruments, computer-based systems, data com-  
munications equipment, remote sensor systems,  
vehicle and portable electronics.  
programmable logic and FPGA’s. No minimum  
load is required. For systems requiring controlled  
startup/shutdown, an external switch, transistor  
or digital logic may be used to activate the remote  
On/Off control.  
  
0.92" x 1.92" x 0.35" open frame package  
  
Wide range input voltages 9-36 and 18-75Vdc  
  
Assembly and attachment for RoHS-6 hazardous  
substance compliance  
A wealth of self-protection features avoid both  
converter and external circuit problems. These  
include input undervoltage lockout and overtem-  
perature shutdown. The outputs current limit using  
the “hiccup” autorestart technique and the outputs  
may be short-circuited indefinitely. Additional  
features include output overvoltage and reverse  
conduction elimination.  
  
Isolation up to 2250 VDC (basic), Q48 models  
  
Up to 30W total output power with  
overtemperature shutdown  
  
High efficiency synchronous rectifier forward  
topology  
The UEI 30W Series includes full magnetic  
and optical isolation up to 2250 Volts DC (basic  
insulation), Q48 models. For connection to digital  
systems, the outputs offer fast settling to current  
step loads and tolerance of higher capacitive  
loads. Excellent ripple and noise specifications  
assure compatibility to circuits using CPU’s, ASIC’s,  
  
Stable no-load operation with no required  
external components  
The synchronous rectifier forward topology  
offers high efficiency for minimal heat buildup  
and “no fan” operation.  
  
–40 to +85°C temperature range; see derating  
  
Certified to UL60950-1, CSA-C22.2 No. 234  
safety approvals, and CE marking on 48V input
