SELV Output This unique, ultra-low-profile module incorporates AC-DC conversion, integrated filtering and transient surge protection in a Two temperature grades including operation to 40C chassis-mount or PCB-mount form factor. Robust package The PFM in a VIA package enables a versatile two-sided thermal Versatile thermal management strategy which greatly simplifies thermal design challenges. When combined with downstream Vicor DC-DC conversion Safe and reliable secondary-side energy storage components and regulators, the PFM in a VIA package allows the High MTBF Power Design Engineer to employ a simple, low-profile design 3 which will differentiate his end-system without compromising on 127W/in power density cost or performance metrics. 4914 package External rectification and transient protection required Typical Applications Small-cell base stations Telecom switching equipment LED lighting Industrial power systems Size: 4.91 x 1.40 x 0.37in 124.75 x 35.54 x 9.40mm Part Ordering Information Output Max Product Package Package Package Input Range Voltage Output Product Grade Option Field Function Length Width Type Voltage Ratio (Range) Current PFM 49 14 x B6 M 24 D0 y z z PFM = A0 = Chassis/Always On Length in Width in B = Board VIA C = 20 to 100C Power Factor Internal Reference A4 = Short Pin/Always On Inches x 10 Inches x 10 V = Chassis VIA T = 40 to 100C Module A8 = Long Pin/Always On PFM in a VIA Package Rev 1.1 Page 1 of 26 08/2018PFM4914xB6M24D0yAz Typical PCB-Mount Applications J 1 24V + 24V 10A +IN +OUT D 1 + 2 x Cool-Power ~ + 3.3V 10A ZVS Buck 85 ++ + MOV PFM4914 264V AC C C C C 4 1 2 3 ~ + Cool-Power 1.8V 8A ZVS Buck IN OUT The PCB terminal option allows mounting on an industry standard printed circuit board, with two different pin lengths. Vicor offers a variety of downstream DC-DC converters driven by the 24V output of the PFM in a VIA package. The 24V 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 required.
