Feedback /
Shutdown
Function
This pin receives a feedback current I FB which is proportional to the PFC circuit output voltage.
The current is for output regulation, output overvoltage protection (OVP), and output undervoltage
protection (UVP).
When I FB goes above 107% I ref , OVP is activated and the Drive Output is disabled.
When I FB goes below 8% I ref , the device enters a low ? consumption shutdown mode.

V control
Control Voltage /
Soft ? Start
The voltage of this pin V control directly controls the input impedance and hence the power factor of
the circuit. This pin is connected to an external capacitor C control to limit the V control bandwidth
typically below 20 Hz to achieve near unity power factor.
The device provides no output when V control = 0 V. Hence, C control also works as a soft ? start
capacitor.

Supply Voltage
This pin sinks an input ? voltage current I vac which is proportional to the RMS input voltage V ac .
The current I vac is for overpower limitation (OPL) and PFC duty cycle modulation. When the
product (I S ? I vac ) goes above 3 nA 2 , OPL is activated and the Drive Output duty ratio is reduced by
pulling down V control indirectly to reduce the input power.
This pin sources a current I S which is proportional to the inductor current I L . The sense current I S
is for overcurrent protection (OCP), overpower limitation (OPL) and PFC duty cycle modulation.
When I S goes above 200 m A, OCP is activated and the Drive Output is disabled.
This pin provides a voltage V M for the PFC duty cycle modulation. The input impedance of the
PFC circuit is proportional to the resistor R M externally connected to this pin. The device operates
in average current ? mode if an external capacitor C M is connected to the pin. Otherwise, it
operates in peak current ? mode.
?
This pin provides an output to an external MOSFET.
This pin is the positive supply of the device. The operating range is between 8.75 V and 18 V with
UVLO start threshold 13.25 V.
