FAN7710V/VL incorporate a preheating / ignition function, controlled by a user-selected external capacitor, to increase lamp life. The FAN7710V detects switch operation from after ignition mode through an internal active Zero-Voltage Switching ZVS control circuit FAN7710VL does not . This control scheme enables the FAN7710V to detect an open-lamp condition without the expense of external circuitry and prevents stress on MOSFETs. The high-side driver built into the FAN7710V/VL has a common-mode noise cancellation circuit that provides robust operation against high-dv/dt noise intrusion.
