Product Description

High efﬁciency

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)

48V secondary output.

Built-in EMI ﬁltering

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 in a VIA package 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 in a VIA package 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.

127W/in³power density
