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 V_NOMfor both outputs

•

Telecommunications

Data communications

Wireless

•

UL 60950 recognized in US and Canada and DEMKO

certified per IEC/EN 60950

Meets FCC Class B and IEC/EN 55022 Class B con-

ducted requirements with external filter
