DC/DC Converter
The PQ60280HEA13 PowerQor^® Exa converter is an iso-
lated, fixed switching frequency DC/DC converter that uses
synchronous rectification and a patented topology to
achieve extremely high efficiency and power density. This
module is ideally suited to support wireless base station
amplifiers and for applications to drive cooling fans used in
networking systems, servers and data storage units. The Exa
series converters offer industry leading useable output power
for any standard “half-brick” module. The 28Vo modules are
available in open frame and baseplated versions. RoHS
compliant (see page 13).

derating
• Input voltage range: 35V – 75V, with 100V for 100ms
input transient capability
• Fixed frequency switching provides predictable EMI per-
formance
• On-board input and output filtering
Mechanical Features
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)

4.3oz. (123 grams)
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
• Remote sense for the output voltage compensates for
output distribution drops
• Output voltage trim permits custom voltages and voltage
margining
