DESCRIPTION
The LX1697 is a high performance CCFL controller optimized for wide input voltage range notebook display back lighting applications. Its brightness control architecture supports Intel’s DPST (Display Power Saving Technology) that adjusts the brightness as a function of video
content.
Digital Dimming duty cycle is controlled by providing either a dc voltage or a digital PWM signal to the BRITE_D pin. Burst frequency can be controlled either by the on chip burst oscillator or directly by a low frequency PWM logic signal at BRITE_D.
The LX1697 includes a built in 5.1V regulator so it can be operated directly from the battery without the need of an external 5V supply from the system. The controller’s power stage consists of direct coupled full bridge high voltage drivers for the external N-channel high side and N
channel low side power FETs.
