TIDA-00443: Input cap design

Part Number: TIDA-00443

In section 4.2.6, the switching frequency used is 98 kHz instead of 100 kHz. What’s the reason for this.

If we look at the schematic, it is found that two 0.68 uF caps are used. Could you please let me know why two caps are used.

Also, the two caps are not placed in parallel between the same points. L3 comes in between the two caps. Why is this done.

Kindly explain.

Thank you.
