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.
