Description
The FAN7311 provides all the control functions for a
series parallel resonant converter as well as a pulse width mod-
ulation (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 FAN7311 uses a new patent-pending phase-shift control.
