DC/DC Converter  
Input  
The PQ55540HTL05 PowerQor®® Tera half-brick converter is  
a next-generation, board-mountable, isolated, fixed switch-  
ing frequency DC/DC converter that uses synchronous recti-  
fication to achieve extremely high conversion efficiency. The  
power dissipated by the converter is so low that a heatsink  
is not required, which saves cost, weight, height, and appli-  
cation effort. The Tera series converters offer the maximum  
useable output power for a standard “half-brick” module.  
The 54V Tera units are designed to be used primarily in  
Power over Ethernet (PoE) applications. RoHS Compliant (see  
page 12).  
Operational Features  
PQ55540HTL05 Module  
• Ultra-high efficiency, 93% at full rated load current  
• Delivers up to 275 Watts of output power with mini-  
mal derating - no heatsink required  
• Input voltage range: 38V – 55V suitable for 48V bus  
applications  
Protection Features  
• Input under-voltage lockout disables converter at low  
input voltage conditions  
• Fixed frequency switching provides predictable EMI  
• Output current limit and short circuit shutdown protects  
performance  
converter and load from permanent damage  
• Active back bias limit prevents damage to converter  
from external load induced pre-bias  
• Output over-voltage protection  
• Thermal shutdown  
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 0.34” (8.7mm), permits better airflow  
and smaller card pitch  
• Total weight: 2.6 oz. (75 grams)  
Safety Features  
• 2250V, 30 Minput-to-output isolation  
• UL/cUL 60950-1 recognized (US & Canada), basic  
insulation rating  
• TUV certified to EN60950-1  
Control Features  
• On/Off control referenced to input side (positive and  
negative logic options are available)  
• Meets 72/23/EEC and 93/68/EEC directives  
• Meets UL94V-0 flammability requirements  
• Remote sense for the output voltage compensates for  
output distribution drops  
• Output voltage trim permits custom voltages and voltage  
margining
