KIT6W18VP7950VTOBO1

KIT6W18VP7950VTOBO1 is a 6W bias supply evaluation kit. In power supplies that are used for server, telecom, and industrial applications there is typically a small bias power supply in addition to the main power converter. This 6W bias board is designed to run in a system where it is continuously powered from the 400VDC 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.

• 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 18V and a secondary side unregulated 18V 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 440VDC
• Output voltage is 18VDC (pri. + sec. side)
• Output power max is 6W (pri. + sec. side)
• On-board: CoolSET™ 5th gen. stand-alone controller (ICE5QSAG), CoolMOS™ P7 SJ MOSFET (IPU95R3K7P7)
