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

Details

Date: 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 versus a full bandwidth measurement with additional high frequency bypass capacitor. It is important to verify the voltage ripple directly at the load where usually a high frequency bypass capacitor is used. The video also demonstrates the forced PWM feature of the TPS62135 minimizing the output voltage ripple over the entire load current range.
