KIT6W13VP7950VTOBO1

KIT6W13VP7950VTOBO1 is a bias board that is designed to run in a system where it is continuously powered from the 400V DC output of a boost power factor correction (PFC) converter and provides power to the fan, gate drivers, and controller. This board uses the ICE5QSAG quasi-resonant (QR) flyback controller and the new 950V CoolMOS™ P7 (IPU95R3K7P7). This 950V breakdown voltage gives additional margin in the system to ensure the bias continues to run through surge events. This design was done as a snubberless flyback converter to further improve the efficiency over the entire load range. Suitable for Server and telecom application.

• Auxiliary DC-DC supply featuring off-line SMPS controller IC with 950V CoolMOS™ P7 MOSFET
• Quasi-resonant flyback using a Infineon’s second generation controller
• Snubberless operation to improve efficiency
• 950V breakdown voltage allows operating off of higher input voltages
• Primary side regulated 13V and a secondary side unregulated 13V output
• High efficiency and low cost solution
• Reduced PCB hotspot due to elimination of the snubber network
• Input voltage of board range from 90 to 440V DC
• Output voltage is 13V DC (pri. + sec. side) and output power max is 6W (pri. + sec. side)
• On-board: CoolSET™ 5th gen. stand-alone controller (ICE5QSAG), CoolMOS™ P7 SJ MOSFET (IPU95R3K7P7)
