Output and Input Voltage Ripple and Main Switching Waveforms
The TPS54x80EVM-228 evaluation module output and input voltage ripple
and main switching waveforms at V
I
= 3.3 V, V
O
= 1.8 V, I
O
= 6 A and
Fs = 700 kHz are shown in Figure 2-16. For these waveforms for the
TPS54680 regulator:
Ch.2: Input ripple 100 mV/div.
Ch.3: Output ripple 20 mV/div.
Ch.4: Phase pin 2 V/div.
