... Positive supply voltage input. Although connected to an auxiliary transformer winding, current is supplied from pin 8 (Vstr) via an internal switch during startup (see Internal Block Diagram section not until Vcc reaches the UVLO upper threshold (8.7V) that the internal start-up switch opens and device power is supplied via the auxiliary transformer winding. ...

... FSD210, when Vcc reaches 8.7V the device starts switching and the internal high voltage current source is disabled (see figure 1). The device continues to switch provided that Vcc does not drop below 6.7V. For FSD210, after startup, the bias is supplied from the auxiliary transformer winding. In ...

... Cfb, and the feedback voltage, Vfb, will increase. The input to the feedback comparator is clamped at 3V. Once Vfb reaches 3V, the device switches at maximum power, the 250uA current source is blocked and the 5uA source continues to charge Cfb. Once Vfb reaches 4V, switching stops ...

... Ids Vds Figure 13. Burst mode operation 7. Frequency Modulation : EMI reduction can be accom- plished by modulating the switching frequency of a SMPS. Frequency modulation can reduce EMI by spreading the energy over a wider frequency range. The amount of EMI reduction is directly related to the level of modulation (Fmod) and the rate of modulation. As can be seen in Figure 14, the frequency changes from 130kHz to 138kHz in 4mS for the FSD200/FSD210 ...
