Data Sheet FIAM Filter Input Attenuator Module Features * * * * * * * * TM RoHS Compliant (with F or G pin style) EMI filtering-Class B(1) Transient protection Low profile mounting options 10 and 20 Ampere versions UL, CSA, EN compliance Mini-size package Inrush current limiting 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.
