Function
Input signal for the lamp current control loop. Should be connected to a
voltage proportional to the lamp current.
A capacitor must be connected between this pin and the signal ground. It sets
the time constant of the lamp current control loop.
Input signal for the voltage control loop. Should be connected to a voltage
proportional to the transformer output voltage
A capacitor must be connected between this pin and the signal ground. It sets
the time constant of the voltage control loop.
The IC uses it to make accurate internal currents.
A capacitor must be connected between this pin and the signal ground. It sets
the time that a fault condition is allowed before the IC shuts itself down.
A capacitor must be connected between this pin and the signal ground. It sets
the minimum switching frequency of the full bridge.
