FAN7311BM Datasheet Lcd Backlight Inverter Driver

Manufacturer: Fairchild (now onsemi)

Overview: FAN7311B LCD Backlight Inverter Drive IC FAN7311B LCD Backlight Inverter Drive IC January.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The FAN7311B provides all the control functions for a series parallel resonant converter as well as a pulse width modulation (PWM) controller to develop a supply voltage.

Typical operating frequency range is between 30kHz and 250kHz, depending on the cold cathode fluorescent lamp (CCFL) and the transformer's characteristics.

The FAN7311B uses a new patent-pending phaseshift control.
