Figure 4. Output Voltage
The 1.8V output ripple voltage in PFM mode is shown in Figure 5 . The image was taken with the output
loaded to 120mA and the input voltage set to 3.3Vdc. (Yellow = Switchnode = 2V/DIV, Red = Output
Ripple Voltage = 10mV/DIV, Green = Inductor Current = 500mA/DIV, 2us/DIV)
Figure 5. Output Ripple Voltage
The 1.8V output ripple voltage is shown in Figure 6 . The image was taken with the output loaded to
1500mA and the input voltage set to 3.3Vdc. (Yellow = Switchnode = 2V/DIV, Blue = Output Ripple
Voltage = 10mV/DIV, Green = Inductor Current = 200mA/DIV, 200ns/DIV)
