PRODUCTION DATA
The TPS6287x-Q1 devices have been optimized for inductors in the the range 42 nH to 200 nH. If the transient response of the converter is limited by the slew rate of the current in the inductor, using a smaller inductor can improve performance. However, the output ripple current increases as the value of the inductor decreases, and higher output current ripple generates higher output voltage ripple, which adds to the transient over- or undershoot. The optimum configuration for a given application is a trade-off between a number of parameters. We recommend a starting value of 60 nH to 80 nH for typical applications.
The inductor ripple current is given by:
