MicroRAM – Output Ripple Attenuator Module
Input Voltage: 3 – 30 Vdc
Output Current: µRAM2(xxx)
20 A
µRAM3(xxx)
30 A
Efficiency: Up to 98%
Dimensions (quarter brick): 2.28" x 1.45" x 0.5" (57,9 x 36,8 x 12,7 mm)
Features:
  • >40 dB ripple attenuation from 60 Hz to 1 MHz
  • Integrated ORing diode supports N+1 redundancy
  • Significantly improves load transient response
  • User selectable performance optimization
  • Combined active and passive filtering
  • 20 and 30 Ampere ratings

The MicroRAM output ripple attenuation module combines both active and passive filtering to achieve greater than 40 dB of noise attenuation from 60 Hz to 1 MHz. The MicroRAM operates over a range of 3 to 30 Vdc, is available in either 20 or 30 A models and is compatible with most manufacturers switching converters including Vicor's VI-200 / VI-J00 and Maxi, Mini and Micro series DC-DC converters.

The MicroRAM's closed loop architecture greatly improves load transient response and with dual-mode control, provides precise point-of-load voltage regulation. The MicroRAM supports redundant and parallel operation with its integrated ORing diode function.
