Description
The FAN7300 provides all the control functions for a
series parallel resonant converter and also contains a pulse
width modulation (PWM) controller to develop a supply
voltage. Typical operating frequency range is between
30kHz and 100kHz depending on the CCFL and the
transformer's characteristics.
