1.2.7 Single LC Filter Operation

For applications which do not require the lowest output voltage ripple, the TPS6291x can be operated without the second LC filter. To operate with a single LC filter, replace FB1 with a 0-Ω resistor. The capacitors past the ferrite bead may be removed to reduce the amount of output capacitance, but must be enough to keep the Fco four times below the RHPZ.
