The wide input voltage Synchronizable Constant Frequency rangeof8Vto30V makesit suitabletobe powered
Operation directly from regulated 12-V or 24-V rails, or any
other source with output voltagesin this range. When• Programmable Phase Delaysof Operating usinga 10% accurate regulated 5-V rail,it also canFrequency for Master-Slave Operation be usedin notebook computers or other portable• Lamp Voltage and Lamp Current Regulation battery-powered equipment having lower minimum Analog and Burst Dimming supply voltages. The controlleris capableof driving
