Description

The TPS68000 device provides a power supply controller solution for CCFL backlight applications in a large variety of applications. The wide input voltage range of 8 V to 30 V makes it suitable to be powered directly from regulated 12-V or 24-V rails, or any other source with output voltages in this range. When using a 10% accurate regulated 5-V rail, it also can be used in notebook computers or other portable battery-powered equipment having lower minimum supply voltages. The controller is capable of driving the gates of all 4 NMOS switches directly without the need for any additional circuitry, like dedicated gate drivers or gate-drive transformers. The wide input voltage range also makes it easy to design CCFL converters with higher input voltages like 120 V or 400 V available at the output of a power factor correction unit.
