Line-Voltage Detection
Line voltage detection. The pin is used for PFC multiplier and brownout protection. For
brownout protection, the controller is disabled with a 195ms delay time when the VRMS
voltage drops below 0.8V. There is a 200mV hysteresis for brownout protection.
This pin supplies an over-temperature protection signal. A constant current is output from
this pin. If RI is equal to 24k
, the magnitude of the constant current is 50μA. An external
NTC thermistor must be connected from this pin to ground. The impedance of the NTC
thermistor decreases whenever the temperature increases. Once the voltage of the OTP pin
drops below 1.2V, the SG6980 is off, and auto restarts when the voltage is back to 1.4V.
The resistance of a resistor connected between RI and ground determines the switching
frequency. A resistance between 15k
and 40K
is recommended. The switching
frequency is equal to [1560 / RI] kHz, where RI is in k
Ω
. For example, if RI is equal to 24k
Ω
,
then the switching frequency is 65kHz.
Current Amplifier Output internal sawtooth and determines the pulse width for PFC gate drive.
Inverting Input for PFC

result in excellent input power factor via average-current-mode control.

PFC Current Amplifier
and Output of Multiplier
average-current-mode control.
Peak Current Limit
The peak current setting for PFC.
This pin receives the external switching signal. The PFC switching can be synchronized by
SYNC with 1:1 ratio.
Active high. The SG6980 is disabled whenever the voltage at this pin is lower than 1V or the
pin is open. When SG6980 is disabled by ON/OFF, the I
DD
current is lower than 35μA.
Ground
The ground.
The totem pole output drive for the PFC MOSFET. This pin is internally clamped under 18V
to protect the MOSFET
.
The power supply pin. The threshold voltages for start-up and turn-off are 12.5V and 10V,
respectively. The operating current is lower than 5mA.
This pin outputs a ready signal to control the power on sequence. Once the SG6980 is
turned on and the FB (PFC feedback input) voltage is higher than 2.7V, this pin locks high
impedance. Disabling the SG6980 resets this pin to the low.
The feedback input for PFC voltage loop. The inverting input of PFC error amplifier. This pin
is connected to the PFC output through a divider network.
The error amplifier output for PFC voltage feedback loop. A compensation network (usually
a capacitor) is connected between this pin and ground. A large capacitor value results in a
narrow bandwidth and improves the power factor.
This input is used to provide current reference for the multiplier. The suggested maximum
I
AC
is 350μA.
