Typical Application Example PIN FUNCTION DESCRIPTION Pin No. SOT223 PDIP7 Pin Name Function Description 1 1 V Powers the Internal Circuitry This pin is connected to an external capacitor of typically CC 10 F. The natural ripple superimposed on the V CC participates to the frequency jittering. For improved standby performance, an auxiliary V can be connected CC to Pin 1. The V also includes an active shunt which CC serves as an opto failsafe protection. 2 NC 3 GND The IC Ground 2 4 FB Feedback Signal Input By connecting an optocoupler to this pin, the peak current setpoint is adjusted accordingly to the output power demand. 3 5 DRAIN Drain Connection The internal drain MOSFET connection. 7 GND The IC Ground 4 8 GND The IC Ground
