DESCRIPTION
The L6560/A is a monolithic integrated circuit in
Minidip and SO8 packages, designed as a con-
troller and driver of a discrete power MOS transis-
tor for the implementation of active power factor
correction, for sinusoidal line current consump-
tion.
Realized in mixed BCD technology, the chip inte-
grates:

... Since the current through R2 doesn’t change, the ∆I current must flow through the capacitor C and enter in the error amplifier. This current is mirrored inside the L6560, and compared with a precise internal reference of 40µA. Whenever such 40µA limit is exceed, the OVP protection is triggered (Dynamic OVP), and the external power transistor is switched off, until the overvoltage situation disappears ...
