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.
