The FAN7310 provides all the control functions for a series parallel resonant converter and contains a pulse width modulation (PWM) controller to develop a supply voltage. Typical operating frequency range is between 30kHz and 250kHz, depending on the CCFL and the transformer's characteristics. The FAN7310 has a patent-pending on phase-shift control.
