Product Description
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.
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.
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.
Typical Applications
•
Small cell base stations
•
Telecom switching equipment
•
LED lighting
•
Industrial power systems

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.
