WEBENCH-POWER-DESIGNER: Webench TPS543620 current limit and Inductor Isat

Other Parts Discussed in Thread: TPS543620, TPS543820, TPS543320


Webench selects an inductor that has an Isat that is lower than the TPS543620 current limit.

When working on the following E2E post (+) TPS543620: Regarding output inductor - Power management forum - Power management - TI E2E support forums

I noticed that the Isat of the selected inductor is lower than the lowest current limit setting of the TPS543620.     

The current limit should always be lower than the inductor saturation current.

I have not checked webench but the TPS543820 and TPS543320 are part of same family as TPS543620.
