Description
FAN7313 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 cold cathode fluorescent
lamp (CCFL) and the transformer’s characteristics.
