The voltage of an auxiliary winding should be applied to this pin to detect the moment when the coil is
demagnetized for critical conduction mode operation. Ground ZCD to shutdown the part.
The FB pin makes available the inverting input of the internal error amplifier. A simple resistor divider
scales and delivers the output voltage to the FB pin to maintain regulation. The feedback information
is also used for the programmable overvoltage and undervoltage protections.
The regulation block output is available on this pin. A compensation network is placed between FB
and Control to set the loop bandwidth low enough to yield a high power factor ratio and a low THD.
The Ct pin sources a 270 mA current to charge an external timing capacitor. The circuit controls the power
switch on time by comparing the Ct voltage to an internal voltage derived from the regulation block.
This pin limits the pulse by pulse current through the switch MOSFET when connected as show in
Figure 1. When the voltage exceeds 1.7 V (A version) or 0.5 V (B version), the drive turns off. The
maximum switch current can be adjusted by changing the sense resistor.
Connect this pin to the pre−converter ground.
The powerful integrated driver is suitable to effectively switch a high gate charge power MOSFET.
This pin is the positive supply of the IC. The circuit starts to operate when V
