Description
The LX1688 is a fixed frequency, dual current/voltage mode, switching regulator that provides the control function for Cold Cathode Fluorescent Lighting (CCFL). This controller can be used to drive a single lamp, but is specifically designed for multiple lamp LCD panels. The IC can be configured as a master or slave and synchronize up to 12 controllers.
Features
Provision to Synchronize Lamp Current & Frequency With Other Controllers
Dimming With Analog or Digital (PWM) Methods (>20:1)
Programmable Fixed Frequency
Adjustable Power-up Reset
Voltage Limiting on Step-up Transformer Secondary Winding
Open Lamp Timeout Circuitry
Switched VDD Output (10mA)
Micro-Amp Sleep Mode
Operates With 3.3V to 5V Supply
100mA Output Drive Capability
Applications
Desktop LCD Monitors
Multiple Lamp Panels
Low Ambient Light Displays
