Description
The FAN7311 provides all the co ntrol fu nctions for a
series p arallel resonant co nverter as well as a pu lse
width m odulation (PWM) controller t o d evelop a s upply
voltage. T ypical op erating fre quency ran ge is bet ween
30kHz and 250kHz, depending on the cold cathode fluo-
rescent lamp (CCFL) and the transformer's characteris-
tics. FAN7311 uses a new proprietary phase-shift control.
