FAN7547A - LCD Backlight Inverter Drive IC
The FAN7547A provides all control functions for a current-fed, push-pull, self-oscillation type converter and also contains a pulse-width-modulated (PWM) controller to develop a supply voltage.
Typical operating frequency range is from 30kHz to 100kHz, depending on the cold cathode fluorescent lamp
