DC/DC Converter
The PQ55530HEB08 PowerQor^® Exa converter is an iso-
lated, fixed switching frequency DC/DC converter that uses
synchronous rectification to achieve extremely high efficiency
and power density. This module is ideally suited to support
the IEEE 802.3af standard for Power Over LAN and VoIP
applications. The 53Vout modules feature 2,250Vdc isola-
tion and low common mode noise. The Exa series convert-
ers offer industry leading useable output power for any stan-
dard “half-brick” module. RoHS compliant (see page 13).
Operational Features
• Ultra-high efficiency, 95% at full rated load current
• Delivers up to 400 Watts of output power with minimal
derating - optional open frame unit available
• Input voltage range: 38V – 55V, with 80V 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)
• Total height only 0.50” (12.7mm) for baseplated unit,
open-frame only 0.420” (10.67mm)
• Total weight: 4.3 oz. (123 grams) for baseplated unit,
open-frame 2.6oz. (75 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
PQ55530HEB08 Module
Protection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from permanent damage
