SLVSFM1 March 2021 TPS62902
The external components have to fulfill the needs of the application, but also the stability criteria of the control loop of the device. The TPS62902 is optimized to work within a range of external components. The LC output filters inductance and capacitance have to be considered together, creating a double pole, responsible for the corner frequency of the converter (see Section 18.104.22.168). Table 8-3 can be used to simplify the output filter component selection. The values in Table 8-3 are nominal values. The effective capacitance was considered to vary by +20% and -50%.
