FAN7315 Description
The FAN7315 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 250kHz depending on the CCFL and the transformer's characteristics. 1.0.1 ©2004 Fairchild Semiconductor Corporation FAN7315 Internal Block Diagram RT OSCILLATOR Output Driver OUTB CT...
