Functional Description and Electrical Characteristics
The duty cycle of the OUTx pin can be calculated from the difference equations:
where
error is the difference between the commanded average current and the measured average current in units
of Amps,
where k indicates the integral number of PWM periods that have elapsed since current regulation was initiated.
