7.13 Overpower or high/low line compensation
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 mains detect input current on the PROTECT pin and outputs a
proportionally dependent current on the ISENSE pin. The DC voltage across resistor R3
(see Figure 3
) limits the maximum peak current on the current sense resistor (see
Figure 13
).
At low output power levels, the overpower compensation circuit is switched off.
