The FB pin is the inverting input of the internal error amplifier. An external resistor divider scales the output voltage to the
internal reference voltage to maintain regulation. The feedback information is also used for the programmable overvoltage
and undervoltage protections. The controller is disabled when this pin is below the undervoltage protection threshold,
V
The Control pin is the output of the internal error amplifier. A compensation network is placed between the Control and FB
pins to set the loop bandwidth. A low enough bandwidth is needed to obtain a high power factor ratio and a low THD.
The Ct pin sources a current to charge an external timing capacitor. The circuit controls the power switch on time by com-
paring the Ct voltage to an internal voltage derived from the regulation block. The Ct pin discharges the external timing
capacitor at the end of the switching cycle.
The CS pin limits the cycle−by−cycle current through the power switch. When the CS voltage exceeds the internal
threshold, the MOSFET driver turns off. The sense resistor that connects to the CS pin programs the maximum switch
current.
The voltage of an auxiliary winding is applied to this pin to detect when the inductor is demagnetized for critical conduction
mode operation. The controller is disabled when this pin is grounded.
