3 Performance Data
Figure 3-1 and Figure 3-2 shows the enable and shutdown of the TPSM13604HEVM. See Figure 3-3 for transient response waveforms (1-A to 4-A load step) and Figure 3-4 for output ripple. The default output capacitance configured on the EVM is optimized for an output voltage of 5.0-V and 3.3-V. The output voltage tested below are for an output voltage of 9-V and switching frequency of approximately 300-kHz by placing shunt on J4 Pins 5 and 6, changing R9 resistor to 3.32kΩ and R3 resistor to 232kΩ, and placing shunt on J3 Pins 5 and 6.
