Description
The FAN7311B provides all the control functions for a
series parallel resonant converter as well as a pulse
width modulation (PWM) controller to develop a supply
voltage. Typical operating frequency range is between
30kHz and 250kHz, depending on the cold cathode fluo-
rescent lamp (CCFL) and the transformer's characteris-
tics. The FAN7311B uses a new patent-pending phase-
shift control.
