To set the power limit:
Slew Rate The slew rate is calculated as a function of change in the output voltage and a given
time interval. The maximum slew rate is 1% rated voltage/150us. The slew rate is
saved upon power off and restored at power on. Output ON/OFF and shutdown are
not affected by the programmable slew rate. These functions have a slew rate of
1%/20ms.
The range of output voltage is 5% - 0.1% of rated voltage.
The range of time interval is 1.5 s - 150 us.
The negative slew rate is limited by the discharge rate of the output capacitors.
During current share, slaves operate with their default slew rate. The master operates
at its programmed slew rate. Hence a programmable slew rate for the system is
achieved. However, this slew rate is limited by the speed of the control loop. The
slaves will return to their programmed slew rate when they exit current share slave
operation.
