An effective two-step OVP enables to safely handle overvoltages either occurring at start-up or resulting from load disconnection. Table 2. The information on the output voltage of the PFC preregulator is fed into the pin through a resistor divider. A compensation network is placed between this pin and INV pin 1 to achieve stability of the voltage control loop and ensure high power factor and low THD.
This pin is connected to the rectified mains voltage via a resistor divider and provides the sinusoidal reference to the current loop. Current return for both the signal part of the IC and the gate driver. The high-level voltage of this pin is clamped at about 12V to avoid excessive gate voltages in case the pin is supplied with a high Vcc.
The supply voltage upper limit is extended to 22V min. Table 5. Supply current vs. Supply voltage Figure 6. IC consumption vs. Vcc Zener voltage vs. Tj Figure 5.
