Features & Benefits
Product Ratings
• Universal input (85 – 264VAC)
VIN = 85 – 264V
POUT = up to 400W
VOUT = 24V
IOUT = 16.7A
• 24VOUT, regulated, isolated
• 400W maximum power
• High efficiency
Product Description
• Built-in EMI filtering
The PFM in a VIA Package is a highly advanced 400W AC-DC
converter operating from a rectified universal AC input which
delivers an isolated and regulated Safety Extra Low Voltage (SELV)
24V secondary output.
• Chassis-mount or board-mount packaging options
• Always-on, self-protecting converter control architecture
• SELV Output
This unique, ultra-low-profile module incorporates AC-DC
conversion, integrated filtering and transient surge protection in a
chassis-mount or PCB-mount form factor.
• Two temperature grades including operation to –40°C
• Robust package
The PFM enables a versatile two-sided thermal strategy which
greatly simplifies thermal design challenges.
• Versatile thermal management
When 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 metrics.
• Safe and reliable secondary-side energy storage
• High MTBF
• 140W/in3 power density
• 4414 package
• AC Input Front-End Module provides external rectification
and transient protection (AIM™ sold separately)
Typical Applications
• Small-cell base stations
• Telecom switching equipment
• LED lighting
Shown with required

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.
