LX1688 General 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.
LX1688 Maximum Ratings
Supply Voltage (VDD_P, VDD)....................................................................... 6.5V
Digital Inputs ..............................................................................-0.3V to VDD +0.5V
Analog Inputs ............................................................................0.1V to VDD +0.5V
Digital Outputs .......................................................................... -0.3V to VDD +0.5V
Analog Outputs ......................................................................... -0.1V to VDD +0.5V
Operating Junction Temperature ..................................................................125°C
Storage Temperature....................................................................................150°C
Lead Temperature (Soldering, 10 Seconds) .................................................300°C
Note 1: Exceeding these ratings could cause damage to the device. All voltages are with
respect to Ground. Currents are positive into, negative out of the specified terminal.
