5.1.3 Electromagnetic Emission Reduction
The Buck DMOS power stage is implemented as multiple cells. This allows to control the slope of the power
stage’s current at turn on/off by sequentially turning on/off the cells, achieving a smooth turn on/off and therefore
avoiding high frequency components in the electromagnetic emissions to the battery line. The current slope control
is adjusted internally, the typical current slew rate is 50 ns/A.
