STR6653 - STR-F6653
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 termin
