This pin is connected to an external capacitor of typic-
ally 10 mF. The natural ripple superimposed on the
V
proved standby performance, an auxiliary V
connected to Pin 1. The V
shunt which serves as an opto fail--safe protection.
By connecting an optocoupler to this pin, the peak
current setpoint is adjusted accordingly to the output
power demand.
