Output Voltage Ripple and Noise
Output voltage ripple and noise are defined as periodic or random signals measured at the output pins on
the system board with DC – 200 MHz frequency bandwidth and constant load. Figures 17 – 20 represent
output voltage ripple and noise at characteristic input and output voltages, measured with 200 MHz
bandwidth and 16A constant current load.
