9.5 Available Standby Output Power
The chart below shows the available output power versus line voltage at input power
consumption levels of 1, 2 and 3 watts (respectively). Again, this performance illustrates
the value of ON/OFF control, as it automatically maintains a high efficiency, even during
very light loading. This simplifies complying with standby requirements that specify that a
fair amount of power be available to the load at low input power consumption levels. The
TinySwitch-III ON/OFF control scheme maximizes the amount of output power available
to the load in standby operation when the allowable input power is fixed at a low value.
This simplifies the design of products such as printers, set-top boxes, DVD players, etc.
that must meet stringent standby power consumption requirements.
