CS1601 Pin Assignments Pin Name Pin # I/O Description IFB 1IN 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. STBY 2IN 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 VDD pin. IAC 3IN Rectifier Voltage Sense — A current proportional to the rectified line voltage is input into this pin. The current is measured with an ADC. CS 4IN 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. ZCD 5IN 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. GND 6PWR Ground — Common reference. Current return for both the input signal portion of the IC and the gate driver. GD 7OUT 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. VDD 8PWR 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 (Vz) by an internal zener function. |
