QD48 Dual Quarter Brick Family  
DC-DC Converter Data Sheet  
The new QD48 Family of dual output, 48 V input, DC-DC  
converters from Power-One offers unprecedented per-  
formance in a quarter brick package by providing two in-  
dependently regulated high current outputs. This is ac-  
complished by the use of patent pending circuit and pack-  
aging techniques to achieve ultra-high efficiency, excellent  
thermal performance and a very low body profile.  
In telecommunications applications the QD48 converters  
provide up to 15 A per channel simultaneously - 30 A total -  
with thermal performance far exceeding existing dual quarter  
bricks and comparable to dual half bricks.  
QD48T Converter  
Features  
Unique to quarter bricks, the QD48 converters utilize inde-  
pendent power trains and control functions for each output,  
allowing very tight output voltage regulation and very low  
channel interference. In some applications they can be used  
to replace two single-output quarter bricks.  
•
•
•
RoHS lead-free solder and lead-solder-exempted  
products are available  
Two independently regulated outputs in any combina-  
tion of voltages from 1.2 V to 5.0 V  
Low body profile and the preclusion of heat sinks minimize  
airflow shadowing, thus enhancing cooling for downstream  
devices. The use of 100% surface-mount technologies for  
assembly, coupled with Power-One’s advanced electric and  
thermal circuitry and packaging, result in a product with ex-  
tremely high reliability.  
Simultaneously delivers 15 A per output from 1.2 V to  
3.3 V; 10 A for 5 V output

Minimal cross-channel interference  
Can replace two single-output quarter bricks  
High efficiency – no heatsink required  
High reliability  
The QD48 family provides any combination of standard volt-  
ages from 5.0 V to 1.2 V in an industry standard seven-pin  
package. Outputs can be trimmed from –10% to +10% of the  
nominal output voltage, thus providing outstanding design  
flexibility.  
On-board differential input LC- filter  
Start-up into pre-biased outputs  
No minimum load required on either output  
Available in through-hole and SM packages  
Industry-standard pinout  
The QD48 family is designed to be a drop-in replacement for  
existing dual designs, and utilizes a common trim function for  
both outputs. The converters are also available in a surface  
mount package.  
Industry-standard footprint: 1.45” x 2.30”  
Low profile: 0.26” [6.6 mm]  
Low weight: 1 oz [28 g] typical)  
Inclusion of this new converter in new designs can result in a  
significant reliability improvement over other available duals  
because of its optimized thermal efficiency.  
Meets Basic Insulation requirements of EN60950  
Withstands 100 V input transient for 100 ms  
Positive or negative logic ON/OFF referenced to input  
Fixed-frequency operation

Applications  
Both outputs trimmed via common external trim resis-  
tor, range: +10%/-10% of VNOM for both outputs

ducted requirements with external filter
