Fig. 1: Typical F4804 application schematic with an eighth-brick and quarter-brick converter
(negative ON/OFF logic). Values C1, C2 and Cin depend on the specific converter input and
output voltage.
Fig. 2: Conducted emissions plot (quasi-peak values: "x", average values: "+") for
Q48x30033 in conjunction with F4804 filter. Limits shown are for quasi-peak (upper limit)
and average (lower limit) values. C1 = 2200 pF, C2 = 3300 pF, Cin = 47 μF.
