Output Ripple Waveform
Figure 4
shows the output voltage ripple. This measurement was taken with a very short ground clip and
20 MHZ bandwidth limiting.
Conditions: Input Voltage = 36 VDC Output Current = 2A Bandwidth Limit = 20 MHz
Trace 1: Output Ripple Voltage Volts/div = 50mV
Horizontal Resolution = 2 µsec/div
