Product Description
The PFM in a VIA Package is a highly advanced 400 W AC-DC
converter operating from a rectified universal AC input which
delivers an isolated and regulated Safety Extra Low Voltage
(SELV) 48 V secondary output.
• Two temperature grades including operation to -40°C
• VIA Package
Robust Mechanical Design
Versatile thermal management capability
• Safe and reliable secondary-side energy storage
• High MTBF
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.
The PFM enables a versatile two-sided thermal strategy which
greatly simplifies thermal design challenges.
• 140 W/cubic inch power density
• 4414 package
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.
• External rectification and transient protection required
Typical Applications
• Small cell base stations
• Telecom switching equipment
• LED lighting
• Industrial power systems
