Description
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.
