VCC
Powers the Internal Circuitry This pin is connected to an external capacitor of typic-
ally 10 mF.The natural ripple superimposed on the
VCC participates to the frequency jittering.For improved 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.
