STRF6653 Product details

Description

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 terminal voltage reaches 16 V (typ.), the control circuit enables regulator operation.Once the regulator starts, it draws up to 30 mA from C2 causing the voltage on C2 to fall momentarily.Once the regulat
