DC-DC Converter
The PQ50050HPB50 PowerQor Peta half-
brick converter is a next-generation, board-
mountable, isolated, fixed switching frequency
DC/DC converter that uses synchronous
rectification to achieve extremely high
conversion efficiency.The Peta series converters
offer industry leading output current for a
standard half-brick module. RoHS compliant (see
last page).
Operational Features
• Ultra-high efficiency, 92% at full rated load
• Delivers up to 250W of output power with minimal derating
• Operating input voltage range: 44-52V
• Fixed frequency switching provides predictable EMI performance
Mechanical Features
• Industry standard pin-out configuration
• Size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.50” (12.7mm)
• Total weight: 4.3oz. (123 grams)
Protection Features
• Input under-voltage lockout disables converter at low input
voltage conditions
• Output current limit and short circuit protection
• Active back bias limit prevents damage to converter from external load
induced pre-bias
• Output over-voltage protection
• Thermal shutdown
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
• Output voltage trim range of -20%, +10%
Safety Features
Pending
