STR-F6600 - Off-line Quasi-resonant Flyback Switching Regulators
and Operation The voltage on the VIN terminal (pin 4) controls startup and shutdown of the Series STR-F6600 devices. Figure 1 shows a typical start up circuit. The VIN terminal voltage during startup is shown in figure 2. At startup, C2 is charged through the startup resistor RS. When the VIN term.
