It is not specified for industrial or automotive environments where the ambient regularly exceeds 70°C or dips below freezing.
The LC filter corner and ripple current should be calculated at this frequency. The controller does not support clock synchronization, so multiple units on the same board will beat against each other — plan for input filtering or spread-spectrum if beat frequencies are a concern.
