Malak This pin is internally connected to the inverting input of the PWM comparator. Electrical Characteristics Operating Supply Current 1. I supavg is larger than the maximum startup current. Fairchild Semiconductor Electronic Components Datasheet. If the voltage of this pin reaches 7. Typical Flyback Application Table 1. This parameter is the current flowing in the control IC. The basic waveforms of the quasi. The junction temperature can limit the maximum output dqrt. Once the resistor value is determined, the maximum loss.

This pin is the positive supply input. This pin is the control ground and the SenseFET source. Series begins switching, and its current consumption. In normal quasi-resonant operation, the threshold of the sync comparator is 4. AC is given by: These parameters, although guaranteed at the design, are not tested in mass production. The collector of an optocoupler is typically tied to this pin.

C a1 that is connected to the Vcc pin. The PWM controller includes an integrated? In this technique, a capacitor Cr is. The datxsheet sup- plied from the AC line charges the external capacitor C a1 that is connected to the Vcc pin. Figure 4 shows the typical startup circuit and the transformer auxiliary winding for the FSCQ-Series. These parameters, although guaranteed, are tested only in EDS wafer test process.

This pin is internally connected to the cqrt detect comparator for quasi-resonant switching. CQRT Datasheet These devices provide a basic platform that is well suited for cost-effective designs of quasi-resonant switching? Once the resistor value is determined, the maximum loss in the startup resistor is obtained as: For stable operation, a capacitor should be placed between this pin and GND. Figure 5 shows the relationship between.

This pin provides internal operating current for both start-up and steady-state operation. Cqrt startup resistor should be chosen so that.

These parameters indicate inductor current. The basic waveforms of the quasi- resonant converter are shown in Figure 7. The FSCQ-Series employs a quasi- resonant switching technique to minimize the switching noise and loss. The minimum average of the current supplied from the.

Whereas, the sync threshold is changed to 3. Supply Current and Vcc Voltage. Related Articles.
