SLVS607–SEPTEMBER 2005
The CON_CTRL register is used to force any or all of the converters into forced PWM operation, when low
output voltage ripple is vital. It is also used to control the phase shift between the three converters in order to
minimize the input rms current, hence reduce the required input blocking capacitance. The DCDC1 converter is
taken as the reference and consequently has a fixed zero phase shift.
