Product Description
• High efficiency
• 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
• Safe and reliable secondary-side energy storage
• High MTBF
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.
• 140W/in3 power density
• 4414 package
• AC Input Front-End Module provides external rectification
and transient protection (VIA AIM™ sold separately)
Typical Applications
• Small cell base stations
• Telecom switching equipment
