Product Details

The PQ60050HPB45 PowerQor Peta converter is a nextgeneration, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification 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 application effort. The Peta series converters offer industry leading output power for a standard half-brick module. In addition to typical single ouput voltage applications, the Peta units can also be used to provide a wide input range Intermediate Bus for IBA systems. RoHS compliant (see last page).

Operational Features

• Ultra-high efficiency, 91% at full rated load current
• Delivers up to 225W of output power (45A) with minimal derating - no heatsink required
• Wide input voltage range: 35-75V
• Input voltage transient capability: 100V, 100ms
• Fixed frequency switching provides predictable EMI

Mechanical Features

• Industry standard pin-out configuration
• Standard Size Open Frame:2.40" x 2.30" (61 x 58.4mm)
• Total Open Frame height only 0.43” (10.8mm), permits better airflow and smaller card pitch
• Open Frame Weight: 2.6 oz. (75g)
• Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique

Control Features

• On/Off control referenced to input side (Positive & Neg logic options)
• Remote sense for Vout compensates for output distribution drops
• Output voltage trim permits custom voltages and voltage margining

Safety Features

• UL 60950-1:2007
• CAN/CSA-C22.2 No. 60950-1:2007
• EN60950-1:A12:2011

Protection Features

• Input under-voltage lockout disables converter at low Vin conditions
• Output current limit & Short circuit protection
• Active back bias limit prevents damage to converter from external load induced pre-bias
• Output over-voltage protection
• Thermal shutdown protects converter from abnormal conditions
