VI - MONITOR APPLICATIONS

In most of monitor applications, the power supply must start-up under full load conditions and the stand

-by mode is no longer useful.

The energy of the starting burst must be high enough to ensure start-up, then the capacitor C1 must be

higher in these applications than on TV application (typ. : 1µF).
