Product Highlights
The FIAM is a DC front-end module providing
transient protection, inrush current limiting and
Class B EMI filtering in a Mini-size package. The
FIAM enables designers using Vicor 48 Vin Mini,
Micro, or Maxi DC-DC converters to meet the
transient immunity and EMI requirements of
Bellcore, FCC, ETSI and European Norms and
protect system hardware from inrush current. The
FIAM accepts an input voltage of 36 – 76 Vdc, is
available in 10 or 20 A versions and provides
reverse polarity protection and remote on/off control.
Internally, the FIAM employs a transient suppressor
diode directly across the input. Refer to Figure 1.
This is followed by a passive EMI filter that
provides attenuation of both common mode and
differential mode conducted emissions. Surge
protection and inrush current limiting is
accomplished by a MOS FET in series with the
positive rail whose gate is driven by the charge
pump/control circuit. During normal operation the
FET is fully enhanced; essentially a closed switch.
The charge pump limits the time rate of change of
gate bias voltage at startup, or in the event of a
voltage surge at the input. During this condition, the
source terminal of the FET follows the gate, offset by
the gate threshold voltage. A transient event at the
input, or drain terminal of the FET is therefore
attenuated and absorbed by the FET, which during
this condition is in the source follower mode. As a
result, the transient is virtually non existent at the
output of the FIAM. In addition, upon application of
power, the controlled voltage ramp up, limits the
rate at which the output capacitor is charged, thereby
limiting inrush current.
FIAM is housed in an industry standard "half brick"
module measuring 2.28" x 2.2" x 0.5" and
depending upon model selected, may be mounted
on-board or in-board for height critical applications.
