6 Vin is the converter INPUT voltage,Pin is the converter INPUT power, Po is the converter output power is the efficiency of the it can be seen from the preceding equation, the worst case for system s stability is at Vinmin, so this is the conditionwhich should be considered for the FILTER the FILTER is made of low ESR inductors and ceramic capacitors, it has an important quality factor Q which causes a sharpincrease of the FILTER s output impedance at the resonant frequency and leads to a violation of the stability criteria, causingthe system to break into , the values of RC network has to be adjusted to dampen sufficiently the FILTER s resonance and make itsoutput impedance lower than the converter s INPUT value of the RC network strongly depends on the application s conditions ( INPUT voltage range and total power drawnfrom the source as well as the standards that the equipment has to meet MIL-STD-461 or DO-160 .. ) this becausemeasurements method (LISN) differs from one standard to another affecting the C most applications a low ESR aluminium electrolytic capacitor can be used for damping the network and it s internalESR value will be enough to dampen the INPUT voltage without adding external table hereafter summarizes the recommended capacitor value at 100% output load for various power according toDO160 and to MIL-STD-461 standards.
