C a1 that is connected to the Vcc pin. These parameters, although datasyeet, are tested only in EDS wafer test process. The minimum average of the current supplied from the.
This pin is the positive supply input. In normal quasi-resonant operation, the threshold of the sync comparator is 4. Whereas, the sync threshold is changed to 3. These parameters indicate inductor current.
The collector of an optocoupler is typically tied to this pin. The startup resistor should have properly-rated dissipation wattage. This parameter is the current flowing in the control IC. Figure 5 shows the relationship between.

This pin is internally connected to the inverting input of the PWM comparator. The FSCQ-Series employs a quasi- resonant switching technique to minimize the switching dwtasheet and loss. The current 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 basic waveforms of the quasi- resonant converter are shown in Figure 7.
This pin is internally connected to the sync detect comparator for quasi-resonant switching. Typical Flyback Application Table 1. I supavg is larger than the maximum startup current.
Once the resistor value is determined, the maximum loss in the startup resistor is obtained as: Electrical Characteristics Operating Supply Current 1. Fairchild Semiconductor Electronic Components Datasheet. Once the resistor value is determined, the maximum loss.
AC is given by: These parameters, although guaranteed at the design, are not tested in mass production. Supply Current and Vcc Voltage. In this technique, a capacitor Cr is. If the voltage of this pin reaches 7. The startup resistor should be chosen so that. The junction temperature can limit cq1265dt maximum output power.

Figure 4 shows the typical startup circuit and the transformer auxiliary winding for the FSCQ-Series. The PWM controller includes an integrated?
V acmin — V acmax. The basic waveforms of the quasi. For stable operation, a capacitor should be placed between this pin and GND.
This pin datashedt internal operating current for both start-up and steady-state operation. This pin is the control ground and the SenseFET source. These devices provide a basic platform that is well suited for cost-effective designs of quasi-resonant switching? Series begins switching, and its current consumption.
