FAN7547A Datasheet Lcd Backlight Inverter Drive Ic

Manufacturer: Fairchild (now onsemi)

Overview: FAN7547A LCD Backlight Inverter Drive IC February 2007 FAN7547A LCD Backlight Inverter Drive.

General Description

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 (CCFL) and the transformer's characteristics.

14-SOP ..
