We are investigating the use of vicor dcdc modules for a 1200W load fed from a high voltage input. The idea is to use a BCM* module, to feed 5 paralleled DCM* modules.
Page 23 of the DCM* module design guide, states that the input filter capacitance to the DCM* module must have an SRF higher than the DCM* module switching frequency (ie 750kHz).
However, the BCM* module datasheet makes no such stipulation for its input filter capacitor. (BCM* module F(sw) = 750kHz).
Do you know why this is?
