UNIT
VR3_Powergood Mask time during
Decay ramp up (exit Decay)
PWM is forced for 30 µs starting 80 µs
after DVS exit, This includes the last 20
µs of the final ramp up steps, and until 10
µs after the internal reference has
stepped up to the final voltage setting.
Forced PWM allows a fast transient
response and smaller output voltage
ripple during the transition.
