1.2.6 Single LC Filter Operation

For applications which do not require the lowest output voltage ripple, the TPSM8291x can be operated without the second LC filter. To operate with a single LC filter, replace FB1 with a 0-Ω resistor. C12 and C13 can be removed to reduce the amount of output capacitance. The total output capacitance must remain within the recommended range in the TPSM8291x 3-V to 17-V, 2-A/3-A Low Noise and Low Ripple Buck Power Module with Integrated Ferrite Bead Filter Compensation data sheet for proper operation.
