Product Details

The PQ50090QGB11 PowerQor Giga converter is an isolated, fixed switching frequency DC/DC converter that uses synchronous rectification and a patented topology to achieve extremely high efficiency and power density. This 9Vout module provides 2,000Vdc isolation and can deliver steady state output current up to 11A. RoHS compliant (see last page).

Operational Features

• High efficiency, 90% at full rated load current
• Delivers up to 11A of output current (99W)
• Input voltage range: 44-52V
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required
• Wide output voltage trim range (-10%, +10%), see trim section

Mechanical Features

• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45" x 2.49" x0.512" (36.8 x 63.1x 13.0mm)
• Total height only 0.536" (13.6mm) for baseplated unit
• Total weight: 2.1oz (58g) for baseplated unit

Control Features

• On/Off control referenced to input side (positive and negative logic options are available)
• Output voltage trim range of -10%, +10%

Safety Features

Pending
• 2000V, 30MΩ input-to-output isolation input/output ground separation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see last page

Protection Features

• Input under-voltage lockout disables converter at low input voltage
• Output current limit and short circuit protection protects converter & load from permanent damage and consequent hazardous conditions
• Active back bias limit provides smooth startup with external load induced pre-bias
• Latching output over-voltage protection protects load from damaging voltages
• Thermal shutdown protects converter from abnormal environmental conditions
