conditions and limits the maximum secondary output under start-up conditions or open-lamp conditions. This eases transformer voltage rating requirements. Set the voltage limit to ensure lamp start-up with worst-case, lamp start voltages and cold temperature, system operat- ing conditions. The BULB pin connects to the junction of an external divider network. The divider network connects from the center tap of the Royer transformer or the actual batte ry supply voltage to the topside of the current source "tail inductor." A capacitor across the top of the divider network filters switching ripple and sets a time constant that determines how quickly the clamp activates. When the comparator activates, sink current is generated to pull the CCFL Vc pin down. This action transfers the entire regulator loop from current mode operation into voltage mode operation.
