APPLICATION NOTES (continued)
Ripple & Noise Characterisation Method
All measurement to be taken with the following components connected to the UUT as detailed below.
50 Ohm coax cable, solder connections one end, BNC plug at the other end.
C1
1μF X7R multilayer ceramic capacitor rated at minimum 3 x the output voltage of the UUT
C2
10μF tantalum capacitor rated at minimum 1.5 x the output voltage of the UUT with ESR of less than 100 milliohms at 100 kHz e.g. AVX TPS
C3
100nF multilayer ceramic capacitor, general purpose
R1
450 Ohm resistor, carbon film, ±1%
R2
50 Ohm BNC termination
T1
3T of the coax cable through a ferrite toroid eg Ferroxcube TN32/19/13-3E25
RLOAD
Resistive load at the UUT maximum rating. Connections via twisted wires.
