APPLICATION INFORMATION

TPS60111 with LC output filter for ultra low ripple
For applications where extremely low output ripple is required, a small LC filter is recommended. This is shown
in Figure 30. The addition of a small inductor and filter capacitor will reduce the output ripple well below what
could be achieved with capacitors alone. The corner frequency of 500 kHz was chosen above the 300 kHz
switching frequency to avoid loop stability issues in case the feedback is taken from the output of the LC filter.
Leaving the feedback (FB) connection point before the LC filter, the filter capacitance value can be increased
to achieve even higher ripple attenuation without affecting stability margin.
