The natural ripple superimposed on the VCC participates to the frequency jittering. For im- proved standby performance, an auxiliary VCC can be connected to Pin 1. The VCC also includes an active shunt which serves as an opto fail−safe 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 − 65, 100 or 130 kHz Clock Overload?
