KIT6W12VP7950VTOBO1

KIT6W12VP7950VTOBO1 is a 6W bias supply evaluation kit 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) fly back 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. To be used with EVAL_800W_ZVS_FB_CFD7, EVAL_2KW_ZVS_FB_CFD2, EVAL_2KW_ZVS_FB_CFD7, EVAL_2.5KW_CCM_4PIN, EVAL_2K5W_CCM_4P boards. Target application is server and telecom.

• Quasi-resonant fly back 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 12V and a secondary side unregulated 12V output
• High efficiency and low cost solution
• Reduced PCB hotspot due to elimination of the snubber network
• Input voltage range from 90VDC to 400VDC
• Output voltage of 12VDC (prim. and sec. side)
