V
IN
voltage of 10.8 V and 19.8 V.
Figure 4. Measured Loop Response, TPS5430, V
IN
= 12 V
Figure 5 displays the TPS5430EVM-342 output voltage ripple. The input voltage is V
IN
= 12 V for the
TPS5430. Output current is the rated full load of 3 A. Voltage is measured directly across output
capacitors.
