The TPS63036 buck-boost converter has internal loop compensation. Therefore, the external L-C filter has to be selected to work with the internal compensation. As a general rule of thumb, the product L × C should not move over a wide range when selecting a different output filter. However, when selecting the output filter a low limit for the inductor value exists to avoid sub-harmonic oscillation which could be caused by a far too fast ramp up of the amplified inductor current. For the TPS63036 the minimum inductor value should be kept at 1 uH. To simplify this process Table 1 outlines possible inductor and capacitor value combinations.
