PRODUCTION DATA
The external components have to fulfill the needs of the application, but also the stability criteria of the device′s control loop. The TPS62147, TPS62148 are 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 Output Filter and Loop Stability). Table 10-1 can be used to simplify the output filter component selection.
