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

Features

The series is provided in a five-pin overmolded TO-3P style package, affording dielectric isolation without compromising thermal characteristics. 2 3 VIN 1 OVER-.
