7.10 Overpower or high/low line compensation (VINSENSE and
ISENSE pins)
The overpower compensation function can be used to realize a maximum output power
which is nearly constant over the full input mains.
The overpower compensation circuit measures the input voltage on the VINSENSE pin
and outputs a proportionally dependent current on the ISENSE pin. The DC voltage
across the soft start resistor limits the maximum peak current on the current sense
resistor.
At low output power levels the overpower compensation circuit is switched off
(See Figure 10).
7.11 Soft start-up (ISENSE pin)
To prevent audible noise during start-up or a restart condition, a soft start is made. Before
the converter starts, the soft start capacitor C6 (see Figure 4) on the ISENSE pin is
charged. When the converter starts switching, the primary peak current slowly increases
as the soft start capacitor discharges through the soft start resistor (R6, see Figure 4).
The soft start time constant is set by the soft start capacitor value chosen. The soft start
resistor value must also be taken into account, but this value is typically defined by the
overpower compensation (see Section 7.10).
