Link Voltage Sense — A current proportional to the output link voltage of the PFC is
input into this pin. The current is measured with an ADC.
Standby — A voltage below 0.8V puts the IC into a non-operating, low-power state.
The input has an internal 600k pull-up resistor to the V
Rectifier Voltage Sense — A current proportional to the rectified line voltage is input
into this pin. The current is measured with an ADC.
PFC Current Sense — The current flowing in the PFC MOSFET is sensed through a
resistor. The resulting voltage is applied to this pin and digitized for use by the PFC
computational logic to limit the maximum current through the power FET.
Zero-current Detect — Boost Inductor demagnetization sensing input for zero-current
detection (ZCD) information. The pin is externally connected to the PFC boost inductor
auxiliary winding through an external resistor divider.
Ground — Common reference. Current return for both the input signal portion of the IC
and the gate driver.
PFC Gate Driver — The totem pole stage is able to drive the power MOSFET with a
peak current of 0.5A source and 1.0A sink.
IC Supply Voltage — Supply voltage of both the input signal portion of the IC and the
gate driver. A storage capacitor is connected on this pin to serve as a reservoir for oper-
ating current for the device, including the gate drive current to the power transistor. This
pin is clamped to a maximum voltage (V
