2 This unique, ultra-low-profile module incorporates AC-DC conversion, integrated filtering and transient surge protection in a chassis-mount or PCB-mount form PFM enables a versatile two-sided thermal strategy which greatly simplifies thermal design combined with downstream Vicor DC-DC conversion components and regulators, the PFM allows the Power Design Engineer to employ a simple, low-profile design which will differentiate his end-system without compromising on cost or performance RatingsVIN = 85 264 VPOUT = up to 400 WVOUT = 48 VIOUT = with required companion component, AIM (see pages 2-3)PFM in a VIA Package Rev 2 of 24 08/2018 PFM4414xB6M48D0yzz 48 V 5 V 10 V 8 A Cool-Power ZVS Buck2 x Cool-Power ZVS Buck+_+_+_PFM4414+IN IN+OUT OUT48 V+++C1C2C3M1J185 - 264 VACI nlet+OUT OUTAIM1714M2F1 LNMOVT ypical PCB-Mount ApplicationsThe PCB terminal option allows mounting on an industry standard printed circuit board, with two different pin lengths.

3 Vicor offers a variety of downstream DC-DC converters driven by the 48V output of the PFM in a VIA package. The 48V output is usable directly by loads that are tolerant of the PFC line ripple, such as fans, motors, relays, and some types of lighting. Use downstream DC-DC point-of-load converters where more precise regulation is List for Typical PCB-Mount ApplicationsJ1 Qualtek 703W IEC 320-C14 Power InletF1 Littelfuse 8A 250 VAC 5 x 20mm holderM1 Vicor AIM AIM1714BB6MC7D5yzzM2 Vicor PFM PFM4414BB6M48D0yzzC1 Nichicon UVR1J472 MRD 4700 F 63V 22 x 50mm bent 90 x 2 pcsorCDE 380LX472M063K022 4700 F 63V 30 x 30mm snap x 2 pcs orSic Safco Cubisic LP A712121 10,000 F 63V 45 x 75 x 12mm rectangularor CDE MLPGE1571 6800 F 63V 45 x 50 x , 1 or TMOV20RP300E VARISTOR 10kA 300V 250 J 20mm PFM in a VIA Package Rev 3 of 24 08/2018 PFM4414xB6M48D0yzzPFM4414+IN IN+OUT OUTFanRelaysCoin BoxControllerDispensors48V1688C1C2C3J185 - 264 VACI nletM1 AIM1714F1M2+OUT OUTLNMOVT ypical Chassis-Mount ApplicationsThe PFM in a VIA package is available in chassis-mount option, saving the cost of a PCB and allowing access to both sides of the power supply for cooling.
