Achieving low noise and low EMI performance with DC/DC switching regulators


3.1 Power Tips: Measuring Vout Ripple in DC/DC Converters


July 13, 2017
The video explains the measurement set-up for the output voltage ripple in DC/DC converters. It compares the oscilloscope measurement results using 20MHz bandwidth limitation to a full bandwidth measurement with high frequency bypass capacitor. It is important to verify the voltage ripple directly at the load where high frequency bypass capacitors are used. The video also demonstrates the forced PWM feature of the TPS62135 minimizing the output voltage ripple over the entire load current range.
