Electrical characteristics
The total current consumption is given by the following formula:
where I
DD(PWM)
= I
DD(PWM1)
*N
PWM
More generally, the PWM current consumption has to be individually evaluated for each
f
SMED
clock grouping, using the formula below:
where i = f
SMED
clock group index; N
i
= PWM number of the i_th clock group; N
fSMED
=
f
SMED
clock group number.
