Description
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.
