Power down - hold-up time
Even at turn-off the transition is clean, without any abnormal behavior such as restart
attempts or glitches on both the auxiliary and the output voltages. In
hold-up time is also measured at both nominal mains voltages. At 115 Vac (155 Vdc) the
input capacitor (C20) stores enough energy for keeping the regulation for 17.1 mS at full
load, after that the converter loses regulation and the output voltages drop.
The measured time is adequate to provide immunity of the set-top box against standard
mains dip or short interruptions tests, required by standard rules such as the IEC1000, and
protects the unit against loss of channel tuning or video disturbances while the end user is
watching TV or recording programs.
