CCFL BACK LIGHT IC

The FAN7548 provides the necessary circuit blocks to implement a highly efficient CCFL backlight power supply in a small footpirnt 20 SSOP package. The device features two control stages for operating independent resonant tanks for multi-lamp designs.
External parts count is minimized and system cost is reduced by integration such features as a feedback controlled PWM driver stage, the soft start, the open lamp regulation, the open lamp protection, the UVLO, and the self-synchronization circuitry between the buck and Royer stages. It includes an internal Shunt Regulator allowing it to operate with input voltage from 9 to 30V. It supports Analog and burst dimming modes of operation. It providees the open lamp regulation, and the open lamp protection.
